• VW Golf - VW emmissions fix 6 Feb 2017 (Forum)
   Why does there appear to be so much hassle when the new programme fails? Why cannot the dealer admit defeat and simply reinstall the original ECU programme and at least put his customer back to where he was before? Surely this cannot be illegal as many owners are declining the fix as word spreads. You cannot trust anybody, read today that the TV people may be rigging their Electric consumption!

• 2010 ford mondeo 163 titanium x - manifold pressure feedback 24 Nov 2015 (Forum)
  Hi Guys, I have an intermittant amber warning (Engine malfunction) which does not show on restart. I have no fault codes appearing when interrogating the ECU and the engine runs normally whether the fault indication is present or not. The only thing that does not make sense is the feedback from the manifold pressure sensor when the engine is static. The reading is -0.8Hg.this is a significant vacuum reading with engine at a standstill.
• Old Saab 9-3 2.2 TiD - Adding extra gauges 6 Mar 2015 (Forum)
  Where best to insert the senders/sensors, either specific to this engine should anyone reading this be familiar with it, and are there any senders already extant which could be exploited/piggy-backed (I assume the ECU receives some of those values anyway). Many thanks - braniff7
• Astra 1.7dti fan relay fault 28 Jun 2014 (Forum)
  My Astra 1.7dti suffered from a flat battery I started it using jump leads then when I disconnected the leads the car shut down. I've had the fuel pump ecu replaced a new alternator and battery, yet the EML is still illuminated apparently reading fan relay faults the air con isn't working either. I've replaced the fan contol unit with a second hand one and still have the same fault could I have two faulty fan relay units or is there something else I should look at.

• Ford Fiesta - Fiesta won't start - possible computer fault. 11 Nov 2013 (Forum)
  The breakdown guy found the following fault: P060C "internal control module main processor performance", which from net searches appears to be generic. I'm not sure if it's the ecu or what to try next? Any help appreciated.  
• I Have a Question about 'Blue Fin' 8 May 2011 (Forum)
  I have recently bought a 57 plate Mondeo 2.5 T. Should i spend another £400 on a 'Blue fin' from Superchips which would alter the ECU and give me 260bhp rather than the 220 currently available? Apart from an increase in my insurance, are there any other problems with doing this? Will it damage my engine or reduce its life span?

• 1999 Jaguar S Type 3ltr - wiring diagrams 9 Jun 2010 (Forum)
  I have traced the wiring which seems ok to the bulkhead but cant seem to find it again under the passenger footwell where im presuming it should enter the ecu. Autodata doesnt list a wiring diagram for this model so does anybody know of a possible cause for this or know where i can download a wiring diagram?? Thanks for your help.

• Peugeot 306 (1993 - 2001) - 01 2.0 non starting hdi 15 Jun 2009 (Forum)
  It is not a fueling problem on the pumping side, it is on the electrical side. There is no feed going to the injectors to open them, Ecu been checked and is fine so it tends to look more like maybe a broken wire or relay something like that. Anybody got any ideas, will try anything as electrics just baffle me. cheers
• Vauxhall Astra G Petrol (1998 - 2004) - 02 1.6 recurrent EGR fault on an Auto 30 Jan 2009 (Forum)
  http://www.honestjohn.co.uk/forum/post/index.htm?f=4&t=70968 I have had some good advice re: updating the ECU so that it does not look for the EGR valves (this has been confirmed on a number of other forums too). My question is - can I do this even though my car is an automatc? Many thanks in advance

• Peugeot 406 (1996 - 1998) - Scoping the dwell on coil packs 21 Aug 2007 (Forum)
  How does a novice go about scoping the dwell on his coil packs? I need to calculate both the running and cranking dwell for my car to properly configure the ECU. My friend has a bosch diagnostics terminal (smallish hand held green box of tricks that plugs into most cars about the size of a closed newspaper), this has a scope function and has 2 leads that plug in for the 'multimeter' functions it does.
• Used car purchase - died after 2 days. 31 Jan 2007 (Forum)
  Well, after a grand two days of successful Puma motoring, the little one died. It's been to the local ford dealer who've diagnosed a broken coil pack and ECU and tell me it's a fiver off a grand to fix it. I didn't have any warranty from the used independent dealer I bought it from. But my question is, does anyone know if I have a case for the car being 'unfit for purpose' after 2 days and then needing £1000 worth of work?
• throttle position sensor 306 hdi 13 Jan 2007 (Forum)
  The problem with the car is a ticking noise when using revs up to 3200rpm. I concluded this was the injectors but the ecu doesnt recognise this now. I was wondering what sort of problems a faulty TPS might cause? The car is idling fine but just has the engine noise problem. Is it worth getting one of a breakers year or get a new one?
• HELP !!!!!!! Audi A4 will not start !!!! 7 Nov 2006 (Forum)
  Also the drivers information system is not working along with fuel gauge. I've tried disconnecting the battery for a while but it made no difference. Could it be the ECU ? or one of the million sensors !! Any help would be much appreciated, all the best a rather peed off Benno
