Exhaust change

We changed 3 sections of the exhaust but reused the DPF section on my 500 multijet. We then got the check engine message and dashboard icon shows in yellow. The guy who changed the exhaust says the sensor may need replacing but it was fine before the change. Has he missed a sensor connection? He says there was only one but i thought i saw a pic showing two? Anybody else had a problem after changing exhaust parts?

Re: Exhaust change

Need to get the codes read to see whats going on, its possible its not been connected properly but its also possible its been either damaged or simply failed due to being disturbed in the process. Quick look shows upstream O2 sensor and DPF temp sensor.

Re: Exhaust change

cheers, will see the guy who fitted the exhaust tomorrow. He only remembers one sensor. I'll let him know there are two and have a look with him. The error we were getting was UNKNOWN, which made me think hes attached the wrong sensor (if thats possible) and omitted the other. The car is driving ok just annoying to see a dash light on again! Will let everybody know how it goes.

Re: Exhaust change

ok, so had it diagnosed again and they say it is the DPF temperature sensor showing an open circuit. I will try and source a new sensor and get it fitted to remove the error code.

'Open circuit' would suggest 'not connected'

Re: Exhaust change

A simple resistance test on the sensor would tell you if it's serviceable.

Post Re: Exhaust change

Thanks guys, that's interesting. I will get underneath and check it myself. A quick look on eBay has the sensor 50-60, not cheap especially if it's unnecessary. Will post my findings

Re: Exhaust change

Finally got around to checking the sensor. It was connected. So took it to a fiat specialist as I didn't want to buy the wrong sensor. They confirmed it was faulty and had resulted in not increasing the fuel to perform a DPF regency. So had to pay a small fortune (350) for diagnostic check, software endured regen, new temp sensor and new glow plug. However, car runs nicely now, no eml showing.

Fingers crossed we get a few trouble free months motoring. Would I recommend a fiat to anyone, no. Does the VW Up have reliability issues, of the i10? It's a better looking car than either of them but I,'d sooner have a stress free life.

Having two Citigos in our family fleet and now a Panda and Citigo - I can comment on the Up vs Fiat. The VW Up based car has a solid well made looking interior but rear suspension noise after a year of driving, juddery clutch, seats that give no support and a gutless engine means I wouldn't recommend it. It's easier to drive around town than the Panda but frustrating on the open road. Passengers seem to prefer the Citigo as it has an interior with a big-car feel but as drivers we all go for the Panda keys first.
Can't comment on the current i10 but our neighbour got rid of her i10 as it kept cutting out and leaving her stranded. She just didn't trust the car anymore.

I only ever drove Accords (10 of them ) bought them @1 or 2 years old, Honda has stopped importing the Accord so the Mazda 6 was the next best alternative and always petrol engines.

Mazda 6 is a lovely car. Best looking of the medium sized salons too, in my opinion.

Re: Exhaust change

Thanks for the comments. I have never considered a Panda, would you say a Panda is the better small car Fiat do, especially on the open road? My 500 is a 2008 MJD, amybe I bought in at a bad time in the cars life (65,000 on the clock). Maybe we need a new discussion on the forum about when the best time is to buy a 2nd hand Fiat.

If I replace this car next year for around 5k am I buying trouble in the form of another 500? Would 5k on a Panda give me an easier life?

They're based on the same platform as I understand. I got a Panda as it suits my needs -it's a lot more practical, the ground clearance is excellent so it means I can drive down the green lane to the allotment, the visibility and driving position suit me too. However as the mechanicals underneath are very similar I would say to expect the same level of reliability which is around average based real long term reliability data. I don't like diesel engines so I can't comment on those but I've found the petrol Fiats to be very dependable. My last Panda I had for 9 years and 90,000 miles. The weak points on it were - exhaust (which needed changing after 7 years and some suspension components, I also needed to replace the radiator after taking a large stone to the front of the car at speed). So I did need to replace parts but the parts were cheap and the car was not off the road long. If you're getting a second hand one look for corrosion underneath the car if you live in an area where they use a lot of salt on the road - Fiats are not well protected against this. There are a fair few low mileage and pre-registered examples of Pandas around so you can get a stonking bargain if you hunt around. I got a pre-registered twin air lounge with a climate pack for nearly 5k off list.
