During start up- rough lide/misfire

[RS6NOR]

I agree that there could be a coil which is not 100%, but there is still moisture in cylinder 3 when standing still over night, while the others are dry... Coils can be an issue here, but can it be the root cause?

ahh dearest watson, good job old fellow!

mines just had service and MOT this morning, bloody CV gator has split, ouch, more money.

[RS6NOR]

I have decided to change the cyliner head gasket. At the same time i will also:

1. Get a full overhaul of the cyliner heads. Change valve seals, tune values and do cold and heated pressure test to ensure there are now cracks.

2. Change ut the hydraulic tensioners on the cam belt which i believe (based on posts on the forum) is casusing the cold weather strat up rattle (less that 1 second).

3. Replace a lambda sensor (after the cat) which is out of order.

4. replace the end sim-ring on the transmission as there is a tiny leak.


Is there anything else i should consider to replace/upgrade when the engine is out?

I think you need to do the tensioners and the camshaft drive chains as well as the tensioners on the belt to get rid of the rattle.

And as for anything else to change - I'd say you'll need to change your bank too knowing labour prices in Norway - I lived there for 5 years and can only remember tears when anything went wrong on my SAAB99 Turbo (was a few years back!)

What is the hourly rate these days??

Thanks Dave,

When you say: change your bank.. do you mean change both lambda banks on the outlet manifold?

The garage is independant and ahev all the M's and S/RS cars running around here. They take 100 GBP/hour.

The Audi dealer (which by the way are crap) takes 130 GBP/hour.

As you say, labour cost in Norway is high. Therefore am i getting prices from Germany and Unit20. Sad that the ferry which ran Bergen-Stavanger-Newcastle is shut down, then Unit20 would be the chosen one. I have not got all the prices yet, still waiting on prices from Germary.

I have asked for prices from Audi Flensburg (found good feedabck from Danish audi owners). Is there another shop i should evaluate in Northern part of Germany?

You are right. My wording was not the best. Planning to replace tensioners and camshaft drive chains... Tensioners on the timing belt has was replaced at 120k KM.

There is http://www.rsquattro.com/ in Belgium that I hear good things about.

You could ask Carsten at Wagner Engineering. He knows the big RS players in Germany. I seem to remember him telling me there was an RS6 expert in Essen, but I can't remember any other details.

2. Change ut the hydraulic tensioners on the cam belt which i believe (based on posts on the forum) is casusing the cold weather strat up rattle (less that 1 second).

Not the cambelt, but what Dave said. The cam chain tensioner / VVT valves.

3. Replace a lambda sensor (after the cat) which is out of order.

Change 'em both and the upstream lambda sensors, too.

4. replace the end sim-ring on the transmission as there is a tiny leak.

There are upgraded parts for this.

5. Is there anything else i should consider to replace/upgrade when the engine is out?

EGT sensors.
Gut pre-cats
Front crank oil seal
Might as well do cambelt / waterpump / thermostat
Upgrated TC and valve body? Even a full 517trans box?
Loba turbos? Or remanufactured turbos.
Both rocker cover gaskets

1. Get a full overhaul of the cyliner heads. Change valve seals, tune values and do cold and heated pressure test to ensure there are now cracks.

The best ways of testing for cracks is using penetrant dye or using Magnetic particle inspections.

Sorry - I was a bit cryptic! I was joking that you would need to find a bigger bank to keep your money in to pay for all this!!

Actually the labour rates are as bad as I feared - Audi dealer are generally £120/hour even over here, though Unit 20 and MRC are cheaper.

Still - and RS6 on winter tyres on your snow covered winter roads - now that's my idea of fun!!

Good luck

Dave

[RS6NOR]

Thanks for your clarification

The RS6 on winter tyres is not as much fun as you could expect. it is front heavy so turn in on snow is not pleasant and the ESD system is still playing you tricks when it is disabled with the ESD button. Do you get a decent angle on the car it reduce trottle and it becomes a nightmare to handle.

that migh be a new post from me: How to completely disable ESP...?

[RS6NOR]

In my search for rs6 experts in Germany i got a name from Carsten @ wagner engineering. It is a guy in Düren outside Köln called Michael. Apperently an experienced mechanic with a very good reputation. Anyone in here that have experience using him?

[RS6NOR]

Short update.

I have been in contact with Michael Von Hoegen in Düren outside Köln in Germany. Lined up for a trip to him mid August. Will do the following as the engine is out

1. Change cylinder head gaskets
2. Change can cam chain and hydraulic tensioners
3. Overhaul both cylinder heads and inspect it for cracks ( fingers crossed for no cracks..)
4. Change all lambda sensors
5. Change simring seal on gearbox
6. Gutted pre cats and update ecu
7. Install non res milltek catback
8. Change both EGT sensors
9. Instal upgraded TC (not decided on which type yet... Any experiences to share?)

Jeez...How much will it be?
For TC upgrade, there should be a separate thread or two...Try search.

Get a 517trans TC and valve body.
