Having seen many senior members' responses to prior postings about this problem, first hand experience of my own has to concur - "how right they are"!

W210 E240 Avantgarde Estate - "B" service at my local MB dealership on 28th February 2008. Two days later, the engine just cut-out and dies when on the road - dangerous and damned right annoying!

This occurred infrequently over the succeeding two weeks. Sometimes the engine would re-start after a few minutes - other times much longer.

I was muddling through, having spent thousands on this car since its purchase in June 2007 from a private vendor and just spent £417+ on the B service, I was feeling "brassic" and couldn't face another MB bill!! Have I bought a "pup"?

Monday 17th March, had to travel to Wokingham for a meeting. Engine cut-out when just entering the M4 slip road at J13 5 minutes from home!

10 minutes later, engine started, drove to Wokingham some 30 miles away and no problems. Office car park was full and I blocked everyone else in where I was able to park. Left the office with my MD to go on for our meeting - he said we will go in your car can't get to mine!

Well - embarrassing or what? E240 just would not start! MD and two other burly guys pushed my car to another location out of the way. We jumped into the MD's Bentley Continental GT and were on our way!

Got back to the office two hours later. Tried my car and it started straight away - Ah! thought I, leave the engine running while I nip into the office for 5 minutes - play safe! Left office 10 minutes later - the engine had cut out whilst on tick-over.

I took an hour and a half before I managed to get the engine running again. Left the office and a quarter of a mile later at the railway crossing by Wokingham Station, the barriers were down and I had to stop. The engine cut out again!!!

I was half way across a busy road, partially blocking a level crossing - did I curse? Yes - of course did! So did all the other road users at this busy peak hour traffic period!

Being an "old hand now" with my Mobilo Warranty, I rang MB Rescue. 20 minutes later the rescue lorry arrived and had to park the other side of the level crossing. The car was gingerly pushed across the busy rail line between the barriers going up and down like a fiddler's elbow! (Clearly when they were "up")!

Recovered back to home near Newbury. MB rescue had in the meantime arranged for a MB Technician to come to my home the next morning. (9 am the Technician arrives, I outline the symptoms - he said straight away "Crankshaft Sensor"! Hooked-up his Star diagnostic computer and lo and behold the code fault was "crankshaft sensor".

The Technician had a new one one board his vehicle. In the meantime I told him about my "Catastrophic Engine Failure" and my "Tale of Woe - Exeter and Back?" (previous postings). My old lump was sitting in my garage and he suggested that to save me money he could remove the sensor from the "old" engine and fit in my "new" engine. I mulled this over, the old lump had done twice as many miles (at circa 86k) than the replacement engine, and maybe with the original sensor.

I chose the "wise-course" and went for "new" rather than "used". The new sensor was fitted within some 15 minutes and less than an hour since arriving (including coffees and chats), the technician was on his way! Again my Mobilo Warranty to the rescue! Cost of new sensor £73 + VAT and no expensive MB dealership labour costs incurred!

Not a problem since with this earlier fault, (although it is only 4 days since the new sensor was fitted).

I now "drive with confidence" - new engine, new cylinder head, new service, new bodywork repairs, new sensor! Could life be sweeter?

ANYWAY - THE SOLUTION - CRANKSHAFT SENSOR!

Thought that I might bore you all with the post! :rolleyes:

Thanks for the response Television. As my opening sentence stated "I concur".

There have however been many less-well-informed responses to this problem posted by other Members, suggesting many other possible solutions. Hence my input, rather long-winded but maybe providing some light-hearted reading?

Thanks for sharing. Glad you have a happy ending.

So was the £73 + VAT just for the part or does that include fitting and everything (i.e. diagnosing etc.)

That is what the part cost roughly.

Its always hard giving advice from remote control, some times you just have to read in between the lines and post on instinct

Do they have this part on older cars such as my W126? (1985) does anyone know?

Hi Malcolm,

V8 500SEL

If you have the Russian parts link that will be very helpful. Just had the Garage phone me to say they replaced all parts of pump, Filter, etc, and not getting any electrical impulse. The Car ran (for a few seconds) before Garage towed it in, and I was convinced it was one of these parts which needed to be replaced as there was a continuous noise from the pump even when the car was not running but ignition just switched on. Back to the drawing board and so last chance to resolve the riddle before the axe falls on the grand old Lady of the Road.

Many thanks Malcolm for the link and your time for searching it out.

Not quite as clear as a link I saw for a different model, or its me not being able to fathom exactly what the Sensor looks like. A previous link you sent me for the fuel supply line gave me an item number which was very useful. Tried to get my Merc CD's up on the PC but am having prolems with Adobe Reader early version. Bit of a nuisance as I don't have the car back, to be able to see exactly where this little gremlin is fitted and how it relates to the diagram. Thought I might be able to get one before the Garage returns the beast and ask them to do the job.

Think they've had enough pushing the car around the workbay!

Yes I was disappointed in that it did not show where it is.

It takes the readings grom the flywheel so it must be on the rear top of the engine,,intake side

I will see what i can find

Your Question..............

"Thanks for sharing. Glad you have a happy ending.

My Answer......and thank's to Television for his astute observation!

The Crank Shaft Position Sensor ("the part") was £73 + VAT. Under the Mobilo Warranty, the MB Technician's time, diagnosis, removing the old sensor and fitting the new one (at my home address) was covered by the Warranty at no cost to myself - other than a cup of tea and a cup of coffee I supplied to him!

Hope this answers the question.

Hi Malcolm,

Garage phoned me and when I suggested Crankshaft sensor they discounted it as the problem. They later phoned me to say s/h fuel pump replacement definately not working. Kick myself for not checking it. I was told its fairly new and it looked good. OK So, I get a price for a pump from Merc and its £212. not cheap. What if mechanic is wrong?
Looking on ebay I can find new pumps for considerably less and nearly all the older pre 91 models use a pump number 002 091 9701 which refers to Bosch 0 580 254 910.
Would you believe when I asked for my parts number Merc Dist. said 002 091 9702. (!) Can't even find the VIN/Chassis sequence anywhere in Bosch fuel pump list for 1260372.

Dilemma. The replacement parts assembly was necessary as my fuel pump assembly was badly rusting and its now fitted. I can't get hold of my Scottish friend to find out what model he took the s/h replacement set from, to be sure of getting a matching pump. I can now end up with a £200 part that firstly may not be the right fit, or secondly may not solve the problem if its not the pump.

Hoping by dragging out this thread a flash of inspiration will enter my brain. Asked the Garage to let me know dimensions of present replacement part though I think they must be sick of the sight of my car by now as they've not got back to me.

After a month got the car back with new pump on, and £250 lighter only to find the problem still exists. Tried changing the ICV and found behind the Plenum Chamber the engine looked like it has multicouloured sherbert all over it?? What is this I ask?? Some sort of engine startup spray I suppose. Dried to a powder.

That Crankshaft Sensor, Malcolm, I looked on the russian site for 1985 early 500SEL W1260372A in the hope of finding the Sensor part number but I can't find it.
This sounded as though it is what I need but the guy said check the number first,
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=320227316028

bearing in mind American Cars have their steering on the left I guess it may not be suitable? I haven't actually located where it starts and where it ends. Perhaps it can only be seen from underneath? If, I dare drive it to my trusted Mechanic then perhaps he can fit it for me. Last chance for the old girl as I've totaly lost interest with her now. Pity.

T.D.C. SENDER UNIT,POSITION SENDER UNIT,KNOCK SENSOR,AND GROUND STRAP

Sorry Malcolm I'm feeling a bit dense, which of these listed is the Crank Shaft Sensor that usually causes the problem? none of the diagrams look at all like the cable and two ended ebay item I showed as a link.

Thanks.

Thanks Malcolm is that Bosch direct you are talking about, or Euro Car Parts?
Had another look under the bonnet and darned if I could place this thing or track where it might go to. Like to check the plug end before buying sender. Tried the Merc CD's on a laptop and still could not come up with diagram of the engine with labelled parts to assist me understanding where this thing travels to. Is it to the coil, the Fusebox or a seperate terminal block somewhere.?
Part of the CD didn't want to open so maybe thats why I could not find it.

Sorry to be a pain on this.

It is at the rear of the engine and sits over the flywheel and takes the info from there
