RS6 Inspection... current car on eBay
Posted: Mon Apr 29, 2013 9:38 pm
Hi all,
I've been hanging around in the background for a while and got very close to buying a car on Friday morning but due to the high level of work needed and the asking price, I turned it down.
As I won't be buying the car, I thought I'd put my findings on the here so that anyone else thinking of buying this car could gain from my 1 1/2 hours spent looking over it.
The reg is RS03 TNT and it's currently on eBay being sold as spares or repairs. It's done 138936 miles.
The transmission needs rebuilding. It does drive but as with the other 5HP24A ZF transmissions I've seen, it's got no drive to 1-4th gears. This is a common fault which is due to a bearing failure and then O-ring failure which leads to no oil pressure to clutch pack A (1-4th gears). The result is that the engine revs shoot up and you go no where. Once it's happened for longer than around 5 seconds, the Trans ECU throws up a fault and the gearbox goes into Limp mode (lighting up all of the indicator letters at once). You are then in top gear (5th) with a torque converter that is allowed to slip so that you can drive the car home.
So... onto the other stuff.
I did a compression test. The results were ok ranging from 170psi to 150psi. The lowest cylinder was right rear cylinder (direction etc as sitting in the driving seat). The rest all gave atleast 165psi, even though the battery was dying as I was doing the test. I checked with MRC and 10-11 BAR (that's 147 to 162psi) is normal and perfectly acceptable.
As above, the battery is dying and will probably need replacing.
The plugs have not been changed recently and were fairly seized in. I used some engine oil on the threads to make sure that they didn't gall up going back in or seize in again so they should be ok.
One of the m5 allen bolts has been rounded off that holds a pipe close to the OS coil packs. One of the coil pack bolts threads (in the rocker cover) has been stripped at NSF coil pack.
The vacuum pipe around the engine bay is generally splitting and needs replacing.
The cam chain tensioners need changing as it's got the "grrrr" sound just above idle which comes and goes.
The alloys need refurbishing.
The front passenger door will not shut in any other way than pushing it to... it needs a new lock/latch.
The front bumper looks as though it's been cracked and then repaired. The paint is good but there are telltale signs at the corners close to the headlights where extra material has been added.
The OSF foglight doesn't work, neither does the telltale indicator inside the car.
The OSR arch has a dent.
The brake discs look ok with plenty of material left although the cross-drill holes are blocked.
The suspension looks to have been replaced with Coil-overs. I didn't have time to jack it up and check what colour or make but there is a C-Spanner in with the tool kit.
The centre arm rest lid hinges are broken as is the latch. I priced up a replacement from VW at about £85 plus vat.
The rear seats (black leather with white piping) have had kiddy seats in and have wear marks from the bottom corners. Whether the dents will come out remains to be seen but the leather is worn also.
The rear seat cup holders are broken and the first aid kit is missing.
The warning triangle cover latch is broken on the back of the tailgate.
The warning light for the tailgate is on all of the time despite me checking that the tailgate was definitely shut properly.
The Menu control knob in the centre console doesn't work anything. I seem to remember that it goes through the menu on the dash (as in my old S8) but no matter what I did, I couldn't get anything from it.
In plugging into the car and checking for faults, I found the following:
Engine
17985 - Right Engine mount - open circuit
17831 - Secondary Air Injection System Bank 1, Insufficient flow
17819 - Secondary Air Injection System Bank 2, Insufficient flow
17865 - Exhaust Gas Temp Sensor 2, open or short to Plus - Intermittent
Transmission - obvious faults to do with rebuild being needed.
Radio
No communications - Intermittent
Tyre Pressure
System Switched Off
I priced up a new Exhaust Temp Sensor at around £300 plus vat from VW.
Last but not least, it's last timing belt change was at 97,000 mile with VW so it's overdue a Timing belt service!!
While it wasn't possible to check that the engine performed properly, the test drive (around the block) was ok. No serious rattles or clonks. The engine pulled ok but sounded slightly rough. I'm not an expert on these engines so I can't say for sure if it sounded 'normal' for an RS6. The last one I service (timing belt service) was over 4 years ago and it performed very well.
I offered less than the dealer was prepared to take and I guess I won't be hearing from him again. It's not a bad car, but I estimated that even with me carrying out all of the work (including the gearbox rebuild) I would be spending another £2k on top of whatever I managed to buy it for. If I factored the hours in as well, I may as well go and buy a car for £9.5-10K.
I hope that someone buys it and brings it back to it's best but it's a slightly and unloved example of what I view as being an awesome vehicle.
