I figured I'd post up more or less the CTO of the 2007 A4 up until now. I've had it around 6 months now/4000km, so this is probably a good milestone as any to post up my experiences. All prices are approximate as I'm going by memory. I've marked preventive maintenance and service items in the table below with [MAINT].
Purchase price: R80'000.00
Disclosed flaws: Missing rear wiper arm. "Blocked catalytic converter". Peeling clearcoat on rear passenger door.
Undisclosed flaws: Missing intercooler. Electrical issues. Failing starter motor. High oil consumption. 1x tyre with a sidewall bulge. Failing battery. Fog lights not working. Leaking water bottle. Gearbox oil leak. Heavy fuel smell in cabin. Faulty centre brake light. Boot area side panels broken. Fender liner torn.
Parts replaced:
| Battery | R1800 |
| Battery clamps | R47 |
| Turbo core | R2500 |
| Cargo side panels | R175 |
| Rear wiper arm | R200 |
| Rear brake light | R500 |
| Fender liner | R350 |

| Misc. expenses (nuts, bolts, washers, etc.) | R200 |
That's a grand total of around R9000 in parts/labour that I've had to add on to the car, and around R4500 in maintenance. A lot of the maintenance entries were big ticket items that won't crop up for at least a few more years, and I am sure I am forgetting about a few things here and there, but this is the gist of it. I still need to tackle a couple more things, but I'm taking things as they come.
Would I buy this car had I known about these issues? Honestly,
no. I would have walked away, but what's done is done and at the end of the day, it drives really nicely and I'm still enjoying it and this 'experience' is providing me with a very good opportunity to go over the car and fix things as I find them. I do my own wrenching so I have no labour costs, which I imagine would drive the price up a fair bit. A big part of me wishes that I had sprung for the A4 Avant with the 3.0 TDI engine that was up for sale in my area a few months prior to me purchasing this one, but the cam chain job was due and that is a much bigger job than I am willing to take on at home since it involves complete engine removal.
Next up on the list will be to tackle the leaking coolant flange, change the gearbox oil and try and find a spare intercooler that I am missing. I didn't detail all the fixes here as that would make this wall of text even longer, but most were simple fixes that I could do in my spare time (the fog light fuse was missing, and the fuel pump seal needed tightening, for instance).
I can see why there is a stigma around 'cheap premium cars', but if you are not scared to get your elbows greasy, the CTO isn't too bad, but if you are in a similar position, I'd highly recommend you have the car taken to an independent mechanic for a once-over. Unfortunately, I bought this car from someone one province over, so I only had a friend's word to go on, and I wouldn't have expected him to go digging around the car in too much detail. Lots of the flaws wouldn't have been apparent anyway. So I can only emphasize that one do a very thorough check on cars like these. Best case, you walk away from a lemon, worst case, you have some room to do negotiations
