Audi S4: PH Fleet

Chris's gearbox woes finally come to a (costly) head



So the gearbox was getting worse. I'd found that manually shifting from second to first before coming to a halt smoothed things out considerably, but even that strategy was beginning to fail and it seemed I needed to make a choice, flog the car as an unwell S4, or sort the 'box.

Kept clean in its days as a press car!

Given the overall condition (marginally better than a banger racer), and to avoid being the first man to sell a B8 S4 for £3,500 I chose the latter.

First, but actually for the umpteenth time I tried to locate a specialist who could work on the gearbox, and found no one. VW has done a fine job of restricting extra-dealership meddling with this DSG/S Tronic component. The parts costs a mint and the most common solution appears to either be a new control unit or a replacement 'box. Given the number of VW products using these 'boxes, it's remarkable someone isn't trying to work on them, especially so given specialists like Litchfield are now masters in repairing Nissan GT-R DCT transmissions.

So I hunted and failed and then thought I might just try another oil change, but it had only covered 8,000 miles since the last one, so that seemed pointless. Equally, the level of technical knowledge beyond 'just fit a new gearbox' at dealer level was as you'd expect - zero. So in the full knowledge that I'd modified the car, I phoned Audi UK and asked it their technical bods could look at it and tell me what the best course of action was. They said they would.

At this point I need to remind you of the mechanical condition of the car, and remind myself of the massive boo-boo I made a year ago. I bought the car from a family member, knowing it needed work and, crucially, knowing that the transmission was pretty lumpy for its 58,000 miles. Where I made a VERY expensive mistake was that I underestimated the good will Audi is willing to offer on these cases where the vehicle is out of warranty. I thought I was on my own, but I've heard from several non-warranted DSG cases that have been 'assisted' by Audi. Not paid for in full, but certainly ameliorated. I thought I'd be wasting my breath, so just went on and remapped the engine and went fast and enjoyed the car.

The technician's report read as follows:

"I confirmed the customer's complaint of clunking gear shift when coming to a stop. This is more apparent when the engine and transmission have reached full operating temperature. I carried out a clutch adaption reset on the transmission and retested for around 30 miles. The clunking reoccurred. I then checked transmission oil level and quality which was OK. I attempted to recalibrate the clutch bite point parameters, however the transmission would not allow this due to a fault with the input shaft. In cases like this, we usually recommend replacement of the dual clutch pack and mechatronics unit (valve body and electronic control unit ) together, however, in this instance I would advise a replacement complete transmission unit to be fitted to avoid the possibility of any further problems arising from this issue."

"Can you smell dog?"
"Can you smell dog?"
We have been quoted £4,129 inc VAT for the replacement of the box, which as far as I'm aware is a pretty good rate, although I totally understand that it's still a sizeable sum taking into account the car's value."

So that was the deal. The car's probably worth £13K in the trade, if I'm lucky - so you can work out the percentage of the total value yourself. It's a salutary lesson in the expense of complicated components in modern vehicles, but then I always knew the 'box would present a bill at some point.

And I've had quite a deal here. Hands-up, I'm not sure every S4 owner would receive the same treatment, but equally, they would stand a much better chance of cloaking the engine upgrade and seeking the aforementioned goodwill because there wouldn't be a Youtube video of their car, er, drag-racing an RS4.

However, I still view this as a very, very big bill.

It took a while to fit mind. Audi had the car for several weeks, during which time I suspect they either sent it back to Ingolstadt to show just how much appalling neglect an S4 can handle, or they had a good root around the engine ECU to understand what Revo has done to release so much extra performance. If I was them, I'd have done both!

New 'box cost a big portion of S4's value
New 'box cost a big portion of S4's value
One thing I am certain of, the extra power and torque hasn't caused the demise of the original 'box. It might well have contributed to the speed of its decline, but it was a gonner before I touched the engine.

Now it's back, shifting crisply and the motor remains startlingly strong. The rest of the car is in a right old state. I want to renew the suspension and completely re-bush it and the Revo chaps have kindly provided a new set of front discs and pads. I like exterior shabbiness, I hate mechanical shabbiness and the car is currently feeling a little tired in the chassis department.

When that's done, I have to decide if we keep it or not. I can't think of a better all-round camera car/holdall for the money, but Neil has aspirations for a full-on camera supporting chase machine, and that inevitable has me looking east.

Despite the cost, this is still the best small, fast estate car around.

Not really that expensive when you see how much the chocolate 5 spd tq convertors are in the C5 RS6. Its not just a DSG thing all autos are expensive to replace.

My DSG was faultless along with many friends who have also had DSG cars but I know again of the odd fellow having issues (seatcupra.net)

A DSG box wouldn't put me off. The fact he bought it when it didn't feel right shows in the long run it was knackered in the first place.

Great read & bit comforting to know it probably wasn't down to the upgrades! i have a S4 facelift played around with MTM so was a slightly worrying read at first! Best Small estates around!

The best small, fast estate car around? Hmmmm.... Clearly I'm biased but I'd wager that accolade remains with the Evo IX GT Wagon. You can borrow mine if you fancy a twin test against your S4. Mines about 400bhp so about the same power wise. i think handling and driver involvement though the Evo would walk it. Manual gearbox and all wink Would be a good test though me thinks.

I expect we will see some odd things start to happen in the second-hand car market in the next few years, as more & more complicated cars depreciate to a point where the cost of parts and repairs fail to make economic sense.

Audi pretty much inspect everything now for mods before doing warranty work. I needed a new mech unit on my car and they had the car in for two days just so that a "mod detection expert" could come down and inspect the car before they would go ahead with the warranty work.

I am pretty sure they know exactly how much power that engine can produce but they (like porsche) are only concerned with marketing and keeping all the relevant models and sub models on the right rung of the ladder power wise and in the correct order.

I would describe the B8 Avant as large boarding on huge given how much it has grown over the RS2


regardless of what you have spent Mr Monkey, your costs still are less than what you would have lost in depreciation on an new RS4

most people do not want manual cars for daily drivers, I seam to remember reading that 95% of the final years run of the last M3 where semi auto's

Monkey, great praise for you from Jay Leno on his recent P1 video in case you haven't seen it. Hope you have a new video out soon, been a couple of weeks now.

Gearbox tech seems to be a weakness of VAG it seems to me.

Ask anyone, anyone at all in the trade ( or any owner ) about the CVT multitronic transmission fitted to front wheel drive, non Quattro Audi's. It is a bloody awful box and there are many, many, many disgruntled Audi dealers around the world testifying what a piece of crap it is.

Vorsprung durk Technik, my arse.

And if it was a manual so beloved of the Flat Earth section, how much would a DMF clutch cost fitted to a car like this £2.5K? Then when the gearbox goes......
Doesn't seem so bad really.

Ouch! But...

There is a software update relating to abrupt 2 > 1 changes.

There are people working on mechatronic units but not yet the longitudinal versions.

I agree that it doesn't appear to be the power per se causing the problems, there are S4s around running even bigger numbers quite happily.

And for those of us that do? The gearbox is available, just make it an n/c option.
