Hello everyone, this is my first post, and as with most new posts, it has been instigated by a desire for urgent info.
I recently purchased an 04 V2.2 Cdi 150 hp model with 80k on the clock and it was supplied by an independent.
The first day I collected the vehicle and was happily driving home the yellow engine symbol flashed up on the dash and the power dropped to around 30% ( this I now know as 'Limp Mode') I stoped, turned off the engine, turned it on again and it was fine, only for it happen again 5 mins later. I took the vehicle back to the dealer and he said he would have a look at it. A few days later it was ready for collection. The D said it was a clogged up waste gate on the turbo, it's been cleaned and it's all ok.
Driving home again, same thing happens, I take back to the D again, this time D changes the Turbo for a new one!!...
Since then I've had 1500 trouble free miles, that was until this weekend.
I was on a 150 mile run when shortly after filling the screen wash bottle (for the first time) the yellow engine light came on and Limp mode cut in, the main difference this time form the previous times was, turning the engine off and on again did not clear the yellow light or dissarm the Limp mode.
I took it to the main Merc dealer the next day and they told me a fault code showed the EGR valve needed to be replaced, and promptly gave me a quote of £490 to replace it. I called Motorplan, the warranty Co. provided by the dealer. They told me EGR valves are not covered which left me the problem of financing the repair.
After trawling through various MB forums it appears a very common theme seems to keep cropping up and that is stories of people spending large somes of money on MB dealership misdiagnoses which has led me to question my 'broken' EGR valve.
I have checked that all the rubber air tubes connecting the EGR with various other bits and pieces and are all clear and 'kink' , 'split' free.
I've sucked the tube connecting to the EGR and this lifts an arm connecting to the back of the turbo, additionally it holds the arm in the elevated postion when you clamp the tube, ruling out any small leaks etc.
On further investigation I noticed some small loose rubber hoses, one coming from a small motor on the side of the screen wash bottle and another tube, which had been cut which led to a disabled headlight washing system. The small length of pipe connected to the scren wash bottle was around 250mm long and seem to exit directly onto to EGR valve solenoid just behind the nearside headlight. When I filled the bottle up it then proceeded to empty 50% of it's contents over the solenoid.
I'm just putting two and two together here, this fault only occured after the bottle was filled up and the water leaking out of the tube was squirting directly on to the solenoid. I've taken out the solenoid and cleaned it, dried it but the yellow light will not clear nor the Limp mode.
Any possible insight, suggestions, similar experiences (unlikely) would would truley be appreciated.
Thanks Guys
