sounds like timing issues...cambelt slip or just timing off...
when was the cambelt done last time on that v70r?

edit: one of my colleagues is a trained mechanic and he always says, that if all of the sensors are malfunctioning, then none of them does... so look for the stuff between the malfunctioning sensors...

I suppose it is possible some dope has put the belt on without lining up the marks - but unlikely ? Really is not that difficult is it ?

Timing belt replacement is top of the list of priorities for next week or so

Where about in town are you - me Forest Gate ?

As the diz rotor and leads need doing in any event will be interesting to see where we stand post replacement

I have limited road time as well - alternater knackered - booked in on Tuesday, as I could not do it any cheaper myself. Garage might have a view on poor running also

Have you checked for air leaks? Even the smallest vacuum leak can cause annoying problems.

the garage will check on it for you then. I mean, theyll hear the car going in that something isnt right, so theyll look at it, and hopefully give a proper diagnostics. Honestly, I wouldnt even mess around until you get to the service.
It is unlikely, but belt slippage is always possible, that would delay timing after the timing has been set.
im in catford, the other side of the river, but not that far

What is the history behind this car? is it FWD or AWD? Manual or auto?

Was it auto & now manual? vehicle speed sensor is a fault code I have seen with a auto ecu in a manual....

Reading your mail with some interest Big F- sorry the beast isn’t up to par just yet but I know you expected some initial problems – I’m sure you will sort it so the best of luck.
Regards Bob

My recollection on reflection is that if this is faulty the classic symptoms are non start ? Which I do not have she starts on the button every time - albeit limited given I have a knackered alternator as well, just to add into the mix !
Errrr the fault codes....

If you have another car that is working fine then it should ony take 10-15 mins to swap a known working sensor over to test it.

If cap, rotor and leads are due replacement, i reckon that will be it. Btw, how's it going and did all the cd changers work out ok?
I'm back in a Volvo again, V70r AWD- i'd stick a picture up but still can't make it happen!

Stuart good to hear from you and yes worked good I still have 1 dud I buy 2 or 3 from you ?

P she is an unadulterated manual AWD with prop disconnected of course but intact

Just. Back from test drive following replacement diz rotor and leads

Started her up and she immediately started purring at just under 1000 rpm as she should do. Thought great problem solved, however a mile later did just what she did on the M6 sudden loss of power and then stall.

Would then not start

Dusconnet MAF she started and I crawled home. Nit looked for any DTC as I have roasted my bits off already

Any further suggestions ( apart from charge the battery yet again ) gratefully received !
