W210 E320 Cdi

[ROGHAY98]

Can someone please help me i have seen so many conflicting ideas on the site.

I have just brought a E320CDI on the W plate year 2000. I have 2 warnings, Engine oil too high (only happens when been running for 10 mins or so)(checked both electrically and manually and it is fine).

Speedtronic Visit Workshop, car in limp mode at 40mph at 3000rpm. Took it back to where i brought it and they said it was air getting in the system( is this true)

When i turn the ignition on the coil heater light will not go out, still remains on for about 30 secs after i have started the car, also noticed the auto choke does not kick in so sounds like a bag of nails when starting up.

Now the boot release inside the car and on the key fob does not work. I have noticed that the inside right boot well is wet could this be causing a problem and are they prone here to leaks.

Instrument Cluster is also giving arabic looking display on both the outside temp and the gear/time display.

Can anyone tell me of a reputable mercedes mechanic in the Hull area which will save me money on going to mercedes garage direct.

Not a very good start on mercedes for me and starting to regret buying it.

Please help, i know there is a lot of problems there but is there anything that could be causing the other probs.:Oops: :Oops: :Oops:

Hi & Welcome,

The dash issue is unfortunately common, pls take a look here; http://forums.mercedesclub.org.uk/showthread.php?t=25872

Have your main battery tested, this can be the cause of many issues. Take it to a motor factors, and have the capacity tested (testing the voltage is not a reliable indicator of battery condition).

As for the boot, IIRC there is a drain tube in the fuel filler, perhaps its come astray and is waggling around inside?

The glow plug light is likely a failed glow plug. Does it misfire on a cold morning?

Hi,
The engine oil level warning 'overfill' comes on even if there it is 0.25 litre overfilled, so, if somebody has topped the car up its very easy to do. My garage did this and as it was only slightly over the full mark I left it.

As POD suggests the glow plug light remaining illuminated for some time after startup suggests 1 or more plugs require changing (do a search on changing glow plugs on this forum before attempting the change, they can be easily snapped by an inexperienced fitter).

The speedtronic problem could well be battery related. If the battery is past its best and is undercurrent it will affect the cc and speedtronic. I had a problem with not being able to set the cc after the first start of the day and this turned out to be the first signs of the battery failing. The ECU can detect an undervoltage battery and starts to shut non essential ancillary systems down.

I don't think speedtronic would put the car in limp mode this is more likely to be the MAF, It sounds like you need the fault codes reading and clearing and a new MAF.

The engine can be noisy when started at this time of year (how many miles has the car covered)

Hope you soon get these issues resolved, its worth the effort the engine is a gem.

 

[ROGHAY98]

Thank you so far

The car has 126,000 miles on it, As i am not so technically minded can you please tell me what a MAF is and the IIRC as stated above. I will test the battery and see if that is causing some problems, does anyone know if these jobs are going to be expensive.

Thank you all for your responses so far.:lol:

MAF or MAS is the airflow sensor. Find a bosch agent and buy the internals you can then swop them out. Alternatively give it a clean following PODs excellent thread here; http://forums.mercedesclub.org.uk/showthread.php?t=25775
I just bought a new battery for mine for £69.50 on a Sunday at a garage in the SE. Around £120 from MB but cheaper elsewhere especially the Commercial dealers. As long as you go for a good make (Varta etc) and the same rating you should be fine. Pls have a search on here though with regard to changing batteries as you can cause some expensive problems if you get it wrong.

The MAF is the filter that samples the air temp and adust the fuel ratio to suit
When they go down the car can go into the limp home mode,you could try cleaning as shown in the engine section or a new one From MB they cost £250, from bosch they are only £58.

Re the battery they can cause lots of problems , they mainly fail in that the voltage drops to around 11.75 volt causing circuits to give false readings.

The best way of checking is with the engine running where the voltage should be 13.8 volt , anything much under that then do change the battery,the chances are its the original and past its best now.

3 yr 2000 E320 CDIs batteries failing in the same week, I think there is a conspiracy. I blame the dodgy petrol I wonder if I have a claim

 

[ROGHAY98]

Is there any sites that point you to reputable mechanics that deal with mercedes so i do not have to pay merc dealer prices

Thank you all again for the replies so far

The voice of experience....

Speedtronic visit workshop......just had it, turned out it was the gear selector servo went wrong, car would go to 40mph at 3000rpm, would only go in 2nd gear. Changing from D to R was impossible, was necessary to turn off, shift to N and start up again and then select R.

The other time this happened was the MAF but the car would do 60mph and just felt like there was no turbo....[true, it was in limp mode, turbo would not kick in]. Main dealer charged about €80 for the part plus some time fitting.

Coil heater light, means glowplugs, one or more are failed. Don't try and DIY them, they are prone to cracking in which case the fix is quite messy. Best bet is to replace them all, life is probably about 50-65k. Mine were replaced at about 65k. The bag of nails may possibly be from firing initially on less than 6 cylinders and my guess is she will sound quite horrific initially.

Pixels on the dash, well known, you live with it or replace. I lost a few in the last three months, until then it was fine. You can source one from a breakers yard but there is no guarnatee it will last either.

The oil level sensor was a prooblem, I had an issue under warranty, the original one fitted was faulty and at the time there were others. Garage tried to bill me €400 [about £270] for replacement. The dealer I used at that time I do not use any more, their service manager did not know where it was located.

The water inside I would investigate. There is a corrosion issue you don't want to hear about and it affects doors and wheel arches. It also affects boot lids, around the lock. Take out the boot lining and have a good look, also check the seals. If the car has full MBSH and Mobilo cover then you may get warrnaty cover provided there is no previous accident damage unless such damage was repaired by a Main Dealer. One other point, if you have a sunroof check the drain channels and pipes, in most cars they come down inside rear pillars. If they get blocked water still comes down the pipe but on the outside and ends up in boot. Not difficult to fix or check.

I would go with changing battery, MAF and glowplugs, check/change pollen filer, change transmission fluid unless you are certain it was done. This was to be a sealed for life unit but it has since changed to a recommended fluid change at 60k. You should have a relatively trouble free car. Most of the troublesome items will have been found and repaired by a previous owner. There is a known item, a fan that cools a computer unit, you won't know it is gone but it can cause overheating. If you need more info I can get part number, it was about €140/£90 and needs about 2 hours to fit [over here I pay €85/£55 an hour labour cost].

I've just had the speedtronic fault too.

http://forums.mercedesclub.org.uk/showthread.php?t=25801

Mine is intermitent at the moment, but I think I might go for a battery change anyway.

How much was the gear select unit Olaf?

 

[ROGHAY98]

I keep reading about fault codes, i only know about the warning messages that come up on the dash, where can i get more detailed info on the fault codes for the vehicle. Is there a way of going into the system and pulling the codes off. Thanks to all for your replies so far.

 

[Dom320]

You need a friendly local 'indie' who has the right kit to plug into the car (the plug on mine is in the fuse box under the bonnet). Takes about 30 mins for them to interrogate the memory. Depending on the garage it should cost about £30-£40 (mine only charges £16, and even did it F.O.C. for me the other day ).

 

[ROGHAY98]

does anybody know an indie garage in the hull area.
Many thanks

WBD210026,
I dont know about the fault codes as i dont have the means of getting them from the car, i have only read the comp display.

 

[television]

Ok will look tonight,I will also check on the other faults re engine cutting on another thread. I have got to check on a 226,if i can remember what for.

Many thanks malcom, very much appreciated, all i keep thinking now is what next to go wrong. I got an independant warranty (Customer Protect (Silver Cover)) from the private dealer i brought the car from but i think i have wasted my money, when i get paperwork through i will try and claim off them.
