Hi All,
I've had an issue with a high stationary idle that is intermittent and only occurs when 500 sl has been running for over 1 1/2 hours and I've been researching root causes such as dodgy ACT or idle control. Anyway I have been poking around the engine bay and had a look at the MAF connection and to my horror the good old wiring was shot, disintegration of insulation etc.
Well having read through loads of posts (many state side) I really do believe I need to bite the bullet and get the new wiring harness as it appears through reading, it is just a matter of time before things get worse and I could end up frying the ECU etc.
So my key questions if I may (relating to the UK - South East) are :
Are there any aftermarket harnesses that don't use the dodgy insulation or do I have to try and procure a post 96 harness ? If so is the harness different from a 93 model ?
Who supplies any harnesses in the UK either Merc or aftermarket ?
has anybody on this forum in the UK had theirs done ? If so could you let me know contact details.
Tempted to try installing myself as it appears it is a case of tracing the old one pulling one plug at the time and plugging in new harness as you go. But what is the access to the loom like and do you need to dismantle much of the engine ancillaries ?
Any idea of costs of indy garage to provide loom and install.
Apologies for all the questions but trying to get all ducks in a row.
Many Thanks
Jeremy
