What parts have been replaced?

I would be very surprised if this turned out to be an ECU problem to be honest.

I would be very surprised if this turned out to be an ECU problem to be honest.

Various belts and tensioners. CV joints. Timing belt and water pump. Intercooler. + general service parts and busehes all round including rear axle bushes although I know these are not related, just showing expense incurred.

You may well be right about the ecu but the only way we will know for sure is to put one in. I am hoping that someone on the forum may have a starter kit that we could try.
We are running out of options, I am going on mechanics advice but, if this fails or we cannot get these items i am not sure what i will do.

 

Give me a call in the morning and i'll see what I can do for you

QUOTE (MK4 GTTDI @ Jun 2 2010, 11:56 PM) <{POST_SNAPBACK}>Hoping someone may have some experience with this or may be able to help.
Over the past two months I have had what I can describe as a chugging as I accelerate with power.
I have had it with a main VW dealer who I will never be going near again!! It has been with diesel specialists and general mechanics.
There are no faults what so ever reading on any diagnostics or showing on dash
We have ruled out quite a number of possibilities.

I have now spent €2,000 between parts and labour, I have not been ripped off or anything it is just that we have done a lot of things with this, at one point we even put in a cv joint thinking it may be the fault.

It is really irritating and very annoying to have this issue constantly. We have almost run out of ideas as to what this is. The engine has been completely checked and all seems to be functioning properly. We now believe that it may be the ECU itself and that there may be some glitch in it controlling the rev limiters.

I would like to know whether anyone has had this issue before and what was the cause and resolution....

Also, if anyone has what is called a starter kit - ignition / keys / ecu I would be interested as that is our next move.

Any help will be greatly appreciated.

Thanks, Elliott

 

Have you checked / replaced the injector loom in the cylinder head?

Gearoid I have not replaced this part and I am unsure whether one of the mechanics has done anything with it. What would be the issues with a fault here?

Hi Joe, I was actually thinking of giving you a shout this evening but never got around to it. Will ring you in the morning, thanks.

 

Hi, I would listen to geo and Joe and the likes off here they know there stuff.
I think I have an ecu and stuff off a 03 130 bhp bora.
I def have one off a 02 130bhp a4.

Thanks for the help. Ye I will be contacting Joe tomorrow and see what we can do. If I am going for the ecu I will PM you. Thanks again.

Oil can get in to the loom at the connectors to the injectors, the oil travels up the loom and degrades the wiring, this can cause mysterious misfires without any fault codes.

You can see it in this picture where I cut a wire on a loom I removed last week:

Here you can see the discolouration of the wires all the way up at the connector:

Its only €50ish for the loom and my local dealers had it in stock.

Photos were a good help. I will keep that in mind, and ill mention it to Joe tomorrow if he doesnit see it by then.
I am assuming your car was misfiring? How did you find the wiring fault?

 

Something very similiar to this happened my friend with a 130bhp passat. It turned out to be the ECU

 

I dont know my engine codes, but heres one cheap on adverts http://www.adverts.ie/230992/car-parts-and...-golf-bora-tdi/ (Its probably not the right one but worth a shot!! ).

Goodluck.

Thanks for that. Ye the ECU is def. next on the list, will be trying a new map.

Thanks for the link. Ye as far as I kno the 130bhp and 150 bhp are what I can use in the car, you can't go down in bhp. I think I need ASZ or ASL. I could be corrected though.

 

Arl is the enging code for the 150bhp tdi. I had something similar with my 130 bora. You could be driving along fine and next thing it would give a chuck and go grand then for a bit then give a few more chucks. It showed a fault for cylinder 3 IIRC. Was told it could be either an injector or that loom Gearoid mentioned. Swapped over an injector to see it it was the loom or the injector was at fault. Car went like a dream after that!! Still dont know if it was a bit of dirt on an injector that fell of when swapping it over or a loose connection on the loom. I priced that loom in sponners in roscrea and they wanted E90 for it so if your going to get it, it could pay you to shop around for it.

Ye that sounds just like what I have with mine. Spoke with Joe this morning and he also thinks the same thing. You would hardly be able to put up a pic of how I could swap the injector, is it easy to get in at. Are you driving the 05 going aroun Portlaoise, I passed ya yesterday on the timahoe road, the car is always shining!!

 

Ah i have no pics of doing it. Rocker cover needs to come off IIRC.Tthe injectors are held in with little torx head bolts wihich you dont want to drop down into the block!! They are also very easy to break when you are putting them back in.Ii stripped it down myself but ended up getting my mate who is a mechanic to swap over injectors for me as i didnt have all the tools. My one was showing up a fault do.... Injectors might need to be reconditioned either. I have a haynes manual here that shows how to remove the injectors. They can be got in halfords for about 20 quid. Get the blue one not the green one for the pd engine..

Ya i drive a 05 leon. Was about portlaoise yesterday all right. Had it down in limerick sunday thats why its so clean lol!

Ye I might do that alri. Thanks for the help. It was def. gleamin anyway!!

 

I assume the cam and followers were checked? I saw a PD 150 engine chugging once at a certain rev and what surprised me was it turned out to be the MAF!

What i did was drive the car with MAF plugged in, power was there but so was this chug. I then unplugged the MAF and drove the car, power was gone but the chug could still be felt so that's been ruled out. Havin spoken to a few people now including Joe from Chipped Ireland it looks like it may be the loom as mentioned by Gearoid. I will be checking this over the weekend.

 

How did you get on with this?

Just curious to see if you got it fixed and if so what it was

Only replaced the injection wiring loom/rail last night, had great hopes but unfortunately had no luck.

Was up with Joe this evening and he swapped the ECU so that has also been ruled out. It now looks like it has come down to either of 2 things:
1. being a faulty injector which is more likely or
2. the fuel injection pump. I am just going to put up a post now to see if anyone has injectors for a PD130 and hopefully I can check to see if this resolves the issue.
I'll keep the post going anyway, i'll surely get it sorted soon.

Will be replacing the injectors tomorrow so hopefully that will have a positive result.
It has been said that the valves under the camshaft can give triuble on these cars and the issue would be similar to what I am experiencing, anyone know of this?

Didn't manage to get my hands on the injectors afterwards. Left the car with some lads that were recommended, they took the injectors out and and sent them to Bosch who tested all 4. Result was that 1 injector is breaking down when under high pressure...seemingly this issue is rare as no faults are reading on any dianostics. Anyway this should be the answer to the chugging. Unfortunately it's €600 for a new injector and I can't seem to find any used injectors.

Will have new injector fitted tomorrow. Wondering does anyone know if the injectors from a PD 150 (ARL) would work properly on my PD 130 (ASZ), I am being told that they will put out black smoke and generally not run properly. Unfortunately I don't have the part number from my injectors as they have been sent away but I do have they part number from the 150 if anyone could post the 130 no. it would be great. I have looked up ETKA but there are 2 listed so its not much help.

 

The 150 and 130 injectors on tranverse engines are the same

600 euro for one injector someone is really taking the piss. i know someone who might have a second hand one will let you tomorrow.
