Title: Cutting out when hot no warning lights
Post by: Irmsherelite3.2 on 06 February 2014, 18:09:59
I recently mentioned I had a bit of a water leak from a blocked scuttle panel that drained my battery, I got that sorted and dried out, put car into a local garage for a slight leak from camshaft cover, ever since getting it back it has been cutting out when hot and refusing to start for ten minutes or so then starts and runs fine.

Reading the forums i get the idea it may be a worn crank sensor, or possibly a knock sensor trapped when they have sorted rocker cover gasket.
Any other ideas as i only get fridays off and dont see daylight the rest of the week.

See pedal trick in maintenance, as they guys said.

If you see 0335 (iirc) that is a crank sensor fault.

Sounds like cranksensor, put post up the codes stored in ECU (pedal trick) first.

3.2 takes the cheaper of the 2 cranksensors, around £50 on Tradeclub for genuine part (use genuine GM part for this item, patterns and "Bosch branded" seem to be problematic).

 :-\ Are these "Bosch"  branded not genuine Bosch then ?  As in counterfeit :o :o

I would have thought  being Bosch they would be the same as the GM / Bosch part  . .same Bosch part no.

GM one was £99 .00  + the vat from my local stealer  . . hence I went down  the, what I thought was the genuine  Bosch route

Its hard to tell, but we see a number of people who have cranksensor problems buy Bosch ones from egay (pretty much guaranteed to be counterfeit) or back street factors, and the problem doesn't go away, until they then buy another genuine one.

Like you, I'd imagine that a genuine Bosch one would be almost the same as what they supply to GM (not sure if they make it specifically for GM for things like cable length etc).

IMHO, given that the genuine one for most of us is £46.12 + VAT on TC, I don't think its worth the risk paying £50 for a potentially problematic (fake or just not quite the same as GM) on in order to save a few quid.  Remember, on our V6s, a problematic cranksensor will leave us stranded.

Thanks for reply TB . .   I am concerned now that the one I fitted may not be genuine Bosch . . . . although no problems as yet .

It came in a nice yellow Bosch box  & was sealed in a Bosch part No.  labeled plastic bag  ::) ::)

As the crank sensor had already been changed on my car 35k miles ago , I was able to retrieve the old one complete And compared it to the new so called "genuine Bosch" replacement  . .  it was exactly the same including  length of cable  :-\

Do the GM supplied ones have GM on them as well as bosch then ?

As I don't have another as a spare i will get a GM one ASAP to put in the boot for emergency use

When pricing up the options The alarming man was also quoted £99 + vat from his local stealer :'( :'( . although his & my quotes were retail I believe :-\

I asked the parts guy to check it was the right one as it seemed expensive  . . . his answer was "there is only one listed for the 2.6 and it's £99.00 + vat "   :o :o :o

No error code showing on two readers will try and get a crank sensor today and go from there.

All V6 owners should carry a spare at all times ;D.

As to GM, no idea, not looked that close. However, GM will buy direct from Bosch, so little chance of intermediate wholesalers using a "cheaper source".  To give you some idea of the level of fakes (generally, not just car parts), there was a report a year or so ago that something like 90-95% of branded items on egay were fake.

Oh, and the part number taxi al gave earlier is the correct one for a 3.2. EPC is often wrong on cranksensors if the dealer enables filtering

Sensor changed and running okay but have to admit a bit nervous as only done 20 miles so far, there's a 02 omega up the road for a grand tempted to buy as backup plan..lol
