My shudder has returned.

 

Did you find out what your specialist did to solve your problem?

 

thanks

Hi Alan,  haven't been back to pay him yet! Keep forgetting. Will do and let you know – if he tells me. He plays his cards close to his chest. When I took it in, he manually pumped the fuel pump, and showed me bubbles in the feed pipe, so he may have found that air was getting in somewhere.

Right. he says he fiddled about with the fuel pump. Thinks there may have been an air leak. But he was not convince that he actually found the true fault. However it has been four weeks of daily driving; both pottering into town and long drives, all with no misfiring, so I feel that must have been the fix needed. I suppose he must have tightened something. Sorry not to be clearer, but getting details off him is like pulling teeth.

Oliver used the SAAB specialist in Glossop for his cambelt change

Hi. I am the owner for the last 12 years of a 3.0 DCI Initiale Auto, which has now done 111,000 miles and have had several electrical problems but nothing that stops my delight in the car and a wish to keep it going. However I have had the odd moment where it loses power for a while but usually returns to normal. The Warning light sometimes came on at the time of the problem and sometimes when there was no problem. This usually happened on long journeys and I came to realise when I fuelled up at Sainsburys ( about twice per year). Odd times I have pulled over and it restarts and goes away normally. Lately it has got worse and would not recover at all. I have had the EGR valve blocked off and have replaced the Turbo Pressure Valve and the Intake Flap Valve. It worked OK for 20 miles then stuttered for a few yards then OK for next 20 miles. Yesterday it would not go at all above 25mph. I took it back to the garage and they got a diesel specialist to look at it and he found the fuel pressure was dropping on hard acceleration and increasing again when reducing the throttle. He says either a cracked injector or the fuel pump. Injectors are £220+vat each plus labour. Pump, a lot of money also. I do not want to lose the car but could be spending £3K if we do the injectors and then find it is the pump. Any ideas of the solution to minimise the possibility of taking the wrong direction with this.

Hi

Your symptoms are exactly what mine were. The diagnosis was the solenoid valves in the high pressure fuel pump.

Saab identified the fault and issued a diagnostic and fault fix procedure to their dealers. Renault did not do this which is why Renault dealers don't know what to do about it. The Saab procedure means the job can be done without taking the engine out of the car.

Alan Clarke has posted elsewhere about going to Simply Saab in Bristol to have this fix done so I followed his advice.  I bought the solenoid valves on eBay for £159, and Simply Saab in Bristol fitted them for 5.5 hours costing £363. So total cost £522. One way of looking at this is: the Vel was scrap without this fix and what car can you get for £522? 

So I recommend Simply Saab: they knew the problem, they knew the fix, cos they do about six a year. Phone the Servicing dept on 0117 9406121, Steve is the Service Manager. Website simply-saab.com. They even found a courtesy car, which I declined as my insurance company wanted £25 for the day's cover; instead I took the Park and Ride to the Docks to see Brunel's SS Great Britain.

Cos Bristol is along way from Kendal, I drove down the day before and stayed B&B only 100 yards away in the Beeches Hotel; well recommended. And the Park and Ride is only 5 mins walk away.

BTW the part numbers for the two valves are: SCV 096710-0052 and 096710-0062

Thanks Andrew. What a great piece of news. I will follow this avenue and hopefully sort it out. I am off to Australia tomorrow for a month so will ask my local garage to contact Simply Saab for me. Thanks once again.

Hi Andrew. I would belatedly like to thank you for your advice on my 3.0 dci running in safe mode. My mechanic spoke to the kind mechanic at Simply Saab and he agreed it was the solenoid valves in the fuel pump. These were replaced and it runs like it has never run before for a long time. Great result. Many thanks again.

Hi Pennyfarthing. delighted its worked out well. Like yours, mine runs better than before; it pulls well from about 1200rpm, whereas before it would change down. And on a motorway run I got 49mpg! Have you thought of unblocking the EGR valve to put it back to normal spec? We should meet up some time; I am in Kendal, only about an hour away. Andrew
