ML 270 CDI Strange Kickdown issue - Help!!
Hello all,
I need some help as I cannot understand what is going on with my 2003 Ml 270 CDI.
I took the car to Mercland in Nuneaton today as I needed the MAF replaced (no kickdown and no power above 2500rpm) and at the same time the thermostat was replaced.
The above items were replaced by Nathan (mechanic) and he noticed that one of the injectors needed resealing. I had the additional work done and went on my merry way.
The car kicked down instantly as it did before and the power was back to normal. However, with 400 yards I heard a ticking sound and to cut a long story short, the injector was leaking all over the place.
So back again and Nathan resealed the injector and cleaned up lots of diesel deposits in the engine compartment.
The front of the car was covered with diesel and Mercland kindly offered a wash and I agreed, the valet then asked if I wanted the engine bay washed with some detergent and a hose pipe? I asked if anything could/would be damaged (bearing in mind that the maf had been replaced) and he said no.
So now as you may have guessed, engine bay was cleaned, and as I left the premises........yep you have guessed no kickdown, but the power is still there.
Does the maf need cleaning with electrical contact spray or has it been damaged by the water?
I rang Mercland back straight away and spoke to Nathan the mechanic and he stated that it would naturally dry out.
But how long should/could it take?
I only got the engine bay cleaned as I was assured that no damage would occur.
Pierburg maf was used from ecp along with genuine thermostat from dealer.
Not a happy chap at the moment as I feel the engine bay cleaning has caused the damage.
Any ideas or help would be appreciated
Many thanks
