So... I've an E registration 525e that was built in December 1986.
It doesn't always start (for reasons I cannot make sense of – further details below), which I am thinking is to do with the Cold Start Valve.
I've found differing reports/diagnoses around the internet (including from realoem.com) about where the CSV is situated. I was wondering if anyone on here can tell me definitively...
a. if this car *has* a Cold Start Valve
b. if it does, where it is located (I thought it was by the fuel tank – as my Haynes suggests – but my local mechanic says it's on top of the engine block?)
c. the right part number and where I can get one (emailed a few places and eBayers, but nobody has one so far)
Non-start nonsense – all ideas welcome!
There seems to be plenty of power in the battery (which is new) – the engine turns over but doesn't fire. Mechanic says there's spark.
Once I jump the car, it starts first time and runs fine. Can't understand how this happens if it's a fuel injection issue, but this is what happens!
I tried using a battery charger to boost the battery, but over a six-hour charge the battery level actually fell. Maybe all this sounds more like an electrics issue than a CSV issue – could be there's a power leak?
Just keen to know if any of these problems sound familiar and if anyone has any suggestions, really.
