I've seen one explode before but that wasn't anything to do with the pulley itself. Normally they go noisy and stay noisy and just effect power delivery and fuel consumption.
There's no law that states how long a dephaser pulley will last i'm afraid. One variable that seems to make a huge difference is regular oil and filter changes but I'd personally expect a 100% new dephaser to last a good three to five years with proper regular servicing (Minimum once a year IMO...
You've read the manual regarding the use and function of this system yes? As the vehicle is under warranty I'd take it to your nearest dealer and be done.
Normally I'd agree Oscar but I've just checked a 182 for a customer which had a terrible idle and poor fuel economy and the belts were done by a main dealer (not my place to name drop either party but they are on CS). It was wrong, simple but to make matters worse the cam setting points were...
1 - New key blade if you can remove the broken blade or new locks. I'd try and remove the old one though if you can.
2- Central locking is working indicated by the indicators flashing. You'll need to check that the UCH is sending the actuation command to the locks and also make sure the locks...
Unplug the CTS then but I have never heard of the fuel pump control circuit being governed by engine temp (ever).
Just remember the Mk1 has X2 CTS inputs (one for the dash and a second for the ECU)
It's always a risk you take. You've had enough of them to know the score but sometimes you advise in the interest of the vehicle and longevity but the customer thinks you're just trying to up - sell.
Did you buy it?
Was it me? LoL
It's a tricky one as I genuinely don't know the car or the customer. I know I always check them and try to get the customer to budget for the dephaser. It's rare we do them these days without replacing them though.
In fairness though it could have been fine at the time of the...
Sounds like you've got a power feed the wrong way around... Read the manual carefully and check everything.
Did you need a patch lead? If so it may be an issue in there.
Scott as mentioned above and failing that PC Autos. Both have done work for me in the past and don't mess around with shoddy work. That doesn't mean they're gonna do it for £100 though as proper paint costs!
PC Autos also did a repair and paint job for a customer on a LY R26 and the job was...
Simple enough task on these cars tbh. I would advise you source the bodywork manual though which details exactly how this is done as plastic breaks and from experience isn't cheap to replace with new.
The Mk1 is extremely simplistic (unless it's a Ph3, Renault got sneaky with those).
1 - Disconnect the plug to the fuel pump. Then give it a direct +12v and a good ground by using something like a test probe. Does the pump run?
No - Replace pump.
Yes - See 2 below.
2 - Isolate the circuit and...
I love these issues. Normally simple if you just get all Julie Andrews on them - first question (of many)...
... check the fused link in the + battery terminal. Is it intact visually and using a volt meter does it have a good +12v either side of the link?
