- 1964 S Type Jaguar, 2001 E240 Estate
Hi
I have been careful not to start a new thread before reviewing all similar-sounding problems but have been advised this is the right thing to do here. So here goes!
I am new to Mercs, having fallen for them in place of Jaguars so please be gentle!
The subject: 2001 E240 estate, petrol, 62k miles, bit rough inside from kids but otherwise bought fully tested & lots of history, mainly from Indies, (i think you guys call them!)
Problem:
I have had the car since last December. Bought it with a slight idle misfire but thought a service etc would sort it. While i was thinking about having the service done, the engine management light came on, pulling out from the station car park. Had the service done by a friend who knows Mercs and/but has Sykes hand-held for reading/resetting fault codes etc. He reset 6 faults at the service: sporadic and random(!) misfires, cascading (his words), through Lambda and cat converter failure. After the reset, all was dandy until i AGAIN pulled out from said station car park, engine cold, and going uphill.The engine management light came on and all power was lost. (Limp-home mode?)
I pulled into a layby to let the traffic pass, switched off, started again and although the eng management light was still on, power was resumed, still with idle misfire but back to full power.
This was a couple of weeks ago. 12 new plugs, swopping over coil-packs to try to isolate the misfire, (failed!) and general checking of everything has had no improvement. I reset the faults again, only to have them reappear as above.
Three days ago I jumped in when the car was hot, started it and the eng/management light disappeared! There is still the idle misfire though.
Latest: I did the same car-park thing tonight, but keeping the revs/power low by using Tiptronic manual changes to let the engine warm-up, the b***dy eng/management light came on again, with limp-home mode! Stopped in the same lay-by as before, restarted the engine and, well, see beginning of story!
I have noted a guys, (Maxicab), problems with an E124 and it seems this engine was a pre-curser, (sic!) to the E210 and suffered problems with the top wiring loom.
I have inspected the top loom and it looks good. The injectors seem to be firing but, I have to say, as a marine diesel engineer, the injector 'signature' is not the same for all cylinders. (Maybe this is OK on petrol engines?).
Before i spend more with MB than the car is worth, can anyone point me in a general direction to sort this out?
Many thanks guys!!
