I am writing this review to highlight the terrible experience we had with Slough Audi. We noticed the engine light was on and the car was misfiring, so we called our son who is a senior technician with 27 years’ experience, he did a diagnostic test on the vehicle which revealed that No.2 and No.3 cylinders were misfiring. As we wanted a Haldex service carried out by Audi for online service records we thought we would take it to Slough Audi and have both jobs done at the same time. We booked the car in and a whole day later Slough Audi sent us a quote advising that a repair was required, the ‘removal of spark plugs to check condition’ and then the removal of the injectors for inspection, possible cleaning and advice that the fuel tank should be drained, they said due to the possibility of low-quality fuel being used – we have receipts to prove that we always use Shell V-Power. Two days later my son contacted Slough Audi to discuss the report, and asked if they had checked the ignition coils, the next day they told him that one of the coils did need replacing and that they had been overlooked, in my son’s experience this is the first simple check that should have been done at the start. After 3 weeks and various telephone calls some with no response, they phoned to say it was ready for collection. When we collected it a service manager told us that there had been a smell of petrol, but the technician said it was down to residual fuel and the car was ready to take away. We paid the final bill of £2388.84. When we arrived home my son lifted the bonnet to the strong smell of petrol, on investigation he found petrol dripping from the high-pressure supply pipe to the fuel rail, he also found that the plug had been incorrectly routed and stretched over the low-pressure fuel rail and various cables were not secured. They sent a technician who tried to rectify the fault, this could not be done so the next day they had to send a recovery truck to take it back to the garage. My main concern is that if this had happened to someone without mechanical knowledge, they would have been driving it unaware of a serious fire hazard as we were while driving it home. I find it hard to believe how Audi can charge £185.00 an hour plus VAT for such bad workmanship. We contacted Audi UK, who in turn contacted Slough Audi as they are a franchise. A few days later the after-sales manager Michael phoned who made no apologies just saying that everyone makes mistakes and instead did not care in the least of the stress caused, in his words saying, ‘but is it fixed?’ - from my conversation with him I realised he had not even read our original email properly. After a lot of back and forth he offered us a free service which, in light of this experience, we obviously declined. We will never take our car there again.
