I bought an 06 Vauxhall Zafira CDTi SRi at the beginning of May on Finance and also part exchanging my old car. Before I picked up the car, it had a full service and MOT done by the dealership. The car was also RAC inspected, but this would of been when they had the car. (February 2010) The 1st month of owning the car, it was fine. The 2nd month is when the trouble started. A light on the dashboard appeared (picture of car with spanner) on my way to work one morning, but went off again after a few minutes. The same happened on the way home. The next few days saw the same light appear, but got more intermittent as the days went ahead. At the end of the week, the light had stayed on and I was due to travel to Cornwall on holiday the next day, so I called up the dealership from where I bought the car from and explained what was happening. They advised me that the car only comes with a 1 month warranty. I was not aware of this, and I wasn't offered any extended at the time of sale. The dealership advised I take it a garage across the road which they use for their repairs. I had been doing research online in the week as to what the problem may be, and the EGR valve was tops. I took car to the garage and they cleaned out the EGR valve for as they agreed, this is a common problem with the Zafra. This cost me £45 and no receipt given as it was just 'cleaning'. Anyway, went home and dashboard light appeared again. I assumed that as the valve had just been cleaned, it may not have registered properly, so proceeded on my way to Cornwall with family in tow... Got about 50 miles into the journey and the car started hissing from underneath! I had to pull over as unsure how safe it was! Called breakdown services and the Air intake Intercooler pipe (?) had ruptured. This was replaced, about 5 mins driving again it had popped off. Put back on and a pipe further up the engine came off. It was decided that it would be best to tow me to the nearest garage. Got to a garage and they agreed to take a look at the car and it appears to be the Diesel Particulate Filter that is blocked. I was advised that this can cost around £750+ VAT to get replaced! I then got towed home. I spoke with Trading Standards and they have agreed that the garage I bought the car from is in breach of the Sales of Goods Act as the car it not fit for purpose and not of satisfactory quality. I would expect a 4 year old car to last longer than a month! The service book, it states what oil is to be used and the garage who did the service put in a different one! Unsure if that would make a difference though. I took my car to a diesel specialist for a diagnostics check. There were 4 fault codes which all relate to the DPF. As I took the car out on finance, I contacted the finance company with the faults. They had attempted to contact the dealership I bought from, to no avail. This then resulted in them sending out an independant engineer to inspect the car. Engineer came out. It was a man with a clipboard. About 10-15 mins, he looked at the car, jotted down a few things and that was it. I was expecting a man with a van with some tools/diagnostics kit at least! He came back the next day to take some pictures tho... Engineers report came back, confirming the fault and they said that the DPF was a serviceable item? They offered me £200 towards repair costs. Not good enough as it will cost me considerably more! I decided I would take the car to Vauxhall themselves for a proper inspection. They plugged in diagnostics and done a physical inspection. They have confirmed the DPF is blocked. Cost to fix: £2020 Also, an intake manifold has come adrift. Cost to fix: £909 I contacted the finance company back with the report and have replied saying they have given their final word on it and no further correspondance will be sent unless I accept the £200 goodwill gesture. My car has now been sat in the garage for nearly 4 months as it cannot be driven. My questions: The wrong oil was put in when serviced. It is stated on the service book which oil they used, and bottom of page specifies which oil to use. The DPF is a serviceable item. If this is the case, why was it not picked up when the dealership serviced the car? The car has a full VX service history. Where do I stand? What rights do I have? I really like the car, but its no good to me.
