Save some money and monitor what your car is doing.
This Fiat has come to us on recommendation from another garage with a blocked DPF, now contrary to online myth they don't just go wrong, 99% of the time there is an underlying fault and it is our job to figure this out and stop it happening again. We try and do that whilst also keeping costs to a minimum for the owner.
At the end of the day all we are selling is time. Yes we have lots of expensive equipment, training, years of knowledge, parts go on vehicles, overheads etc etc. But we just sell customers our hours.
I like to run an honest business and keep customer's bills to a minimum which is why when a car is in for diagnostic or fault finding work our very first step is to question the customer and find out as much as we can about what they are experiencing with the vehicle.
Unfortunately in this case the customer hadn't registered the fact that once at cruising speed this car's temperature dropped right down indicating a faulty thermostat, which stops the DPF and other systems from functioning correctly.
How we came to this conclusion was after carrying out all of our regular tests including, diagnostic testing, visual inspections, pressure tests and leakage tests on both the exhaust and inlet system, thermal imaging testing and local road testing we ended up having to do an extended road test, adding more time meaning more expense to the job. This issue did not flag up sat stationary or doing local town traffic driving as the radiator is not exposed to high flowing air.
Now it is fully understandable and reasonable that a driver just wants to hop in the car and drive, as long as the fuel gauge shows fuel not allot else is that important. But if you start to find issues with the car it is well worth taking notice of what is happening with your vehicle. Especially the basics.
The more information we can get from you the quicker we can narrow down any fault meaning we spend less time saving you money
Also you may notice from the pic it was not even 8am and I had already covered over 20 miles, coffee was certainly in order
