Car: A4 Avant TDi 1.9 130bhp. 51 plate 02.
Approaching a roundabout on a duel carriageway at over 80mph - yes I drive too fast - I applied the brakes only to get a solid brake pedal and very little response, I re-applied pushing the pedal as hard as I could, used the gearbox to slow the car and managed to safely stop the car before the roundabout. Luckly the road was quiet, I had plenty of space, was on a good road and I was travelling in a straight line. The car was recover to a my local garage (not audi - i dont like the attitude of my nearest audi garage so use a SEAT garage instead) As soon as I described the problem they knew exactly what was wrong.
The bulkhead housing the servo unit had filled with water, this had entered the servo, master cylinder and break lines. As a result I had to have all the parts replaced along with a new set of discs all round, damaged by the breaking incident, they ended up jammed on, new pads and all brake lines flushed. The bill for this is huge and all because a small drain hole was blocked. A plug in the offending area has now been removed providing better drainage.
Now my point is that the garage were aware of the issue, infact it affects other Volkswagen models including Passat and also Skoda, so if its a know issue easily solved by removing a small rubber bung why havent I had a re-call letter to sort the problem and why was I in a situation which put my life and the life of other drivers at risk. Audi seriously need to address this issue asap before someone really gets hurt.
