Not yet, if it road tests as well as it idles then yes that will be my conclusion.
Smooth yes no scoring but very worn out, surprisingly they are electronically coated , the copper is the base layer with 1 or 2 over the top.
One downside of PD engines. Too much upward pressure on the camshaft. Shell bearings not really up to the job. Probably should be changed with the cambelt.
Hi RAB,
Yes, mine were down to the copper. If not every cambelt change, certainly every other one.
Same thing happened to me, misfire on one cylinder, old harness looked and tested fine, new harness in and all was well again ?
I’m keeping the old one and will try to re wire it. It won’t be long before they are NLA
Thanks for asking Phil, I’ve ordered part 1J0973802 which will take a few days to arrive, I’m just not sure how to attach it to the loom end and a bit scared about breaking it open! I’m in Warrington on Wednesday so will drop by the dealers to see if they have that repair kit you added pictures of to give me a couple of options. Nobody has the sensor end in stock up this way, only to order.
The only other occurrence of misfire I encountered on an AMF, was an injector issue. If you can measure the value’s you can then work out if too much or too little fuel is being pushed through. Way beyond my capabilities but a good VW indy should have the equipment? In my case, replacing 1 injector worked for a few months but then the misfire came back. I did not change the harness on that vehicle though.
I got a set of Darwen-diesel-refurbished AMF injectors fitted to my AMF at ~289000 miles a year ago - that along with a new loom and the injectors being set properly on reinstallation had it idling and running like a sewing machine compared to being somewhat uncultured previously (as well as the occasional revving on start up due to the original injectors being worn). Night and day the comparison - I'm definitely a firm proponent of injector refurbs once the car is past a certain mileage.
VCDS, Engine Controller, Group 13. Shows injector values. Look for an outlier.
I need a handbrake cable fitting, so just messaged my A2 guru and will ask what equipment is needed to test the injector fuelling deviations. My Number 1 injector was initially 2.9 and cylinder 2 was -2.5. After a few minutes all 3 cylinders were within tolerance (I think) between 0.5 and - 0.5. A good bottle of injector cleaner (archoil or similar) and it ran sweet. The loom eventually eradicated all issues for me.
I believe so, it takes an age to get to temperature. Once there it holds fine, fit a new thermostat a couple of years ago.
Thank you, your cable will be difficult or easy depending which fuel tank you have. Present it with an almost empty tank; easier to drop the tank if they have to.
