So I bought a C70 T5 on a 2001 X, which is the year for problems apparently!

Basically, won't idle, just cuts out, but if I get it to rev it misfires and hesitates then cuts out again. Sometimes revs up and down

So, ETM I think (Electronic Throttle Motor), common on this model year

However, if I disconnect the MAF, it'll start and run, albeit abit spluttery and it stinks understandably, but it runs. On idle, the revs will still bounce a little, but it doesn't stall. Reconnect the MAF, back to no idle, cuts out etc

I got a second hand MAF to try, still the same - bought it from a Volvo breakers who said the car they removed it from was ok, but who knows

Now, I get get a brand new apparently genuine Volvo part for £55, this is just eh sensor, no trunking etc which I don't need anyway as the full job lot is Volvo only at £300! To get my ETM reconditioned is £125, plus the ballacbe of removing it

Does this sound like a MAF issue, and I just presume the 2nd hand part was as faulty as mine? Or do I now move onto the ETM and save the money? I cleared the DTCs, and it doesn't run long enough to put new codes in, obv puts MAF codes in when the MAF is removed

Help?!

EML ETC? And service but only after a while of running with no MAF

Update

Changed the MAF, no different

Finally decided to bite the bullet and remove the ETM, ready to send away fro refurb

Raised the car, to find this




Popped the pipe back on, new jubilee and she fired up straight away and ran beautifully!

A £2 jubilee was the problem!
