Hi, I'm going to be changing the engine on an '99 A4 1.9 TDi (AFN) soon, with an engine from a scrap yard. (My existing engine is dead!):blink: Has anyone got experience of doing this swap, so might know of any problems I may encounter? i.e. getting the ecu etc. to work with an engine from...

The saga with this car continues......see previous posts Today on my way to work the engine on my A4 1.9 tdi '98 gave up the ghost. Travelling at around 80-90mph the power dropped off from the car. I moved to the middle lane of the motorway and still no power.....the engine was still...

I've had a mechanic friend have a listen to the noise and he says its one tappet making the noise. Has anyone stripped the cam out to replace along with all the kit (followers/guides/etc.)? Thanks

It sounds like the tappets as on a petrol engine. I am assuming its the same problem. No there have been no performance mods that I am aware of. I think I'm gonna have to strip the lot this friday, so I was wanting ahead start if anyone had an info for me.....

My Audi A4 1.9 Tdi 1998 has developed a ticking noise which sounds like the timing is out. I have ran the vag-com tdi timing checker and it indicates my timing is slighty advanced but within the ok region. Any idea what could be up with the car as I'm not to clued up when it comes to diesel...

The filter is being tightened hard enough......:gun2: If you tighten too much you will force the o-ring seal out of its locating groove.....:tumble:

Yes very weird! :eyebrows: I have ran the vag-com tdi timing checker and it says my timing is slightly advance but within the ok region on the graph. So I dont think its a timing problem. When I got the oil cooler I fitted from the scrap yard, I also took off the threaded tube the filter...

I was wrong.....the oil filter has started to leak again! :no: It would seem the filter is some how becoming loose? Maybe by vibration?? So it looks like I am tightening it every three days!!! :bye: Its an external type filter with a tapped through hole which screws onto the oil cooler...

I got a used oil cooler from a scrap yard and fitted it last night. I screwed the oil filter on hand tight and everything seems ok so far....:icon_thumright: It would seem there was a problem with the oil coolers mating face with the oil filter.....this seemed to occur after a long journey...

Sounds good to me! :yahoo: Thanks again:salute:

Its a '98 a4 1.9 tdi, the filter is an external type with a tapped through hole which screws onto the oil cooler. AFN engine.

I checked the housing which is the oil cooler, surfaces were clean and couldnt see any cracks? So I replaced the filter with a genuine one, tightend it to around 20-30Nm by hand, filled up with oil and then started the engine.......oil started ******* out of the meeting faces between the oil...

I ran the vag-com tdi timing checker today. It shows my timing slightly advanced at tick over. But within the safe area on the graph. Is that a good or bad thing?:sadlike:

My smoke problem is sorted, I fitted a genuine MAF and it runs ok now with no smoke.:moa: Must of had a faulty non-genuine MAF? Thanks inigoy for the help.:icon_thumright:

As well as the problem with a smokey exhaust detailed in another thread, my A4 1.9 tdi ('98) keeps leaking oil from the oil filter? It happened first a month ago, a couple of weeks after an oil service. Oil ended up squirting from the oil filter . Upon inspection the rubber seal on the...

Thanks

I'm gonna try another MAF as I have another genuine one and I think the one that fitted isnt. I am gonna replace the fuel and air filters as the are looking a bit rammy! Will fit this weekend when I get time! The smoke problem I have seems to be getting worse, it is smoking alot more and...

I think it kicks in around 2500-3000 rpm in 2nd gear, I will have to check to verify this. There's a bit of history with this car: I've had a problem with it for some time. I've driven hundreds of miles previous with the turbo boost not kicking in; i.e. the turbo was spinning but I had an...

I have a 1998 Audi 1.9 Tdi with 98000 miles on the clock, at around 2000-2300 rpm the car produces a hell of alot of black smoke. If I then apply full throttle and accelerate it stops smoking? At around this rpm the engine is very lumpy, and basically hits a noticable flat spot briefly with...
