Mercedes Gearbox / Battery Reset – E Class W212/S212

James3 months ago2 months ago06 mins

Ive seen a lot of talk about doing a ‘gearbox reset’ or ‘battery reset’, normally amongst conversation regarding gearbox problems. Gearbox problems can be not changing gear, holding onto gear till high RPM, delayed engagement or harsh / erratic gear change. Occasionally people report issues after having a gearbox service.

What Oil Should I Put In My W212 E-Class

James2 years ago2 years ago13 mins

Introduction When it comes to oil, its a bit of slippery slope if you just put anything in. By not using the correct oil the most probable future problem is carbon build up, probably in the exhaust/DPF, maybe in the EGR system or in the inlet manifold. Using the right oil (at the right intervals)…

W212 ECO Stop/Start & Additional Battery

James2 years ago2 years ago05 mins

Introduction I�ve heard & read a lot about how people think the ECO Stop / Start & additional battery works and it�s time to set the record straight. I think that the most common misconception around this is, that it is this battery restarts the engine once its stopped. It doesn�t. Glad I�ve cleared that…

James2 years ago2 years ago04 mins

Introduction Whilst this problem is not just limited to the E Class, it is certainly a common problem on the OM651 engine.

‘Noise from engine’. E Class W213 – OM654

James4 years ago11 months ago25 mins

More specifically, a ‘ dull plopping noise from the intake manifold – when the air filter is removed’. In our case, all the time – the customer had complained for a little while that the engine was noisy. It sounded a bit odd but there wasn’t anything specific that we could say at that point. Until it got worse and it was at the point that it needed
