Give in and took car to a local specialist who were more than happy to reset the air filter and HFM drift compensation for me. Confirmed the drift values were all to pot so fingers crossed that’s the issue.
Had a bit crack on, nice guys and seem to know their Mercedes cars.
For anyone else...
Easy enough to find out I guess. Job for tomorrow.
Good to know the icarsoft can do the adaptations, I’ve been considering the CR pro so might just bite the bullet.
Thanks foe this reply, so I grabbed an alternative app which is able to read both MAF A and B, see attachment. Both seem to be reading similar. I expect some variation, in fact given one filter was noticeably darker than the other when I changed them I suspect for whatever reason they’re not...
All looks ok. I could only find MAP and Barometric pressure PID’s and both reading correctly.
Question- I hav SAE.MAF and SAE.MAF_A, both are reading differently, MAF is always higher than MAF_A… anyone know the difference? Is one measured and another estimated or is this the two separate MAF...
Fault came on a couple of weeks after an oil and filter change. Air filters were not done and on inspection were pretty bad. I had also noticed smoke under acceleration.
I’ve since changed the filters, turbo seal, breather seal and charge pipe o-rings. No more smoke under acceleration and...
Wait what. I’ve cleaned them - I mean, I’ve sprayed what I thought was the elements from the filter coupling sides with maf cleaner. Are you saying I need to spray them from the turbo coupling end? I see how that could be challenging.
@mersum1es ill grab the pressure sensor data tomorrow...
Intake manifold flaps died years ago, motor is bypassed. EGR is mapped out and have been for 4 years.
Which specific pressure sensors? MAP reading around 102kpa at idle, seems to max out at 254kpa. Boost rises and peaks at 22.6psi.
I’m a little unsure on lambda readings, they always seem to...
Ran data log on a short drive, seems to be working correctly. Peaked at around 3000rpm / 90g/s which I believe to be correct.
Car is driving perfectly, good mpg, good performance, smooth start, idle etc.
Been battling a P0101 fault on my CLS350 CDI OM642 265hp, have cleaned MAF sensors, they appear to be reading ok, have changed filters, changed turbo seals, charge pipe seals etc… all data shows healthy boost levels and car is running perfectly. Just can’t get rid of this engine light so I would...
so today I spent a bit time figuring it out, turns out to be quite a simple fix. You will need a short (less than 8”) T25 torx driver.
Get on your back and look under, there is one bolt clearly visible (labelled as 1) and two more that are not so visible and screw towards the rear bumper...
Any idea how I fix this? The three bolts appear secure however I notice the black plastic bracket on the inside isn’t secured to anything. Looks like there’s no bolt hole for it on the bumper bit.
It’s perfectly secure but is causing a rattle and visually isn’t level.
How are the F1’s in the winter, wet, slush, occasional snow? The conti’s I have on now have very poor grip in the slightest damp but are great in the dry. I want better wet road performance as let’s face it, the north of England is a wet place.
Thanks all. Plenty to look into there.
mines currently on continental sport contacts, they’re useless and have worn at a rate of about -1mm per 1000 miles so not exactly long lasting!
As title, looking for recommendations on all season rear tyres for a CLS350 CDI with stage 1 remap
Need to be decent in the wet as the current tyres, I forget what they are, the Mercedes OE ones, are not great to say the least.
they’re the 280/30 R19’s.
