    I started it up this morning and the idle is all over the place and stinks of eggs. I’ve just cleaned the 3 elements/parts of the maf and run a can of cleaner through the air box and it now revs a lot higher than it was so a change is symptom so could point to the maf still I guess?

        If it stinks of egg would that not be the catalytic converter ??

          Would that cause the poor running? I guess if it’s blocked it could?

            Stink of eggs not always a sign the cat is buggered or running too rich . The Subaru Legacy and the first Volvo's over here in the late 80's stank when being moved about the dealership when brand new.

              The fuel bank 1 wotsit in my experience is usually oxygen(lamda) sensor.

                Just a thought the new ones I referred to having been shunted about not getting warm perhaps the cat was working over time to filter the emissions. So if your lamda sensor isn't setting the lamda and C.O correctly that may be giving you the lovely smell. If you try a lamda get a Boshe or vdub one, not a cheap copy. Been there done that.

                  Cheers si, there was something else that made me think that, when looking at the values I think the lamda sensor was reading -32 may be a red herring of course...

                    That's it. There are always plenty of red herrings with that sort of work.

                      It’s such a genuine little car I can’t wait to get it sorted for her. I wet mopped it yesterday and it looks stunning. (I think).

                        17831/P1423/005155 - Secondary Air Injection System; Bank 1: Insufficient Flow
                        Possible Symptoms

                        Malfunction Indicator Light (MIL) active

                        Possible Causes

                        Fuse for Secondary Air Injection Pump blown
                        Vacuum Hose(s) leaky or collapsed
                        Piping between Secondary Air Injection Pump and Combi (Secondary Air Injection) Valve leaking
                        Secondary Air Injection Solenoid(s) faulty
                        Combi Valve(s) faulty

                        Possible Solutions

                        Check Fuse for Secondary Air Injection Pump
                        Check Vacuum Hose(s)
                        Check Piping between Secondary Air Injection Pump and Combi (Secondary Air Injection) Valve
                        Check Secondary Air Injection Solenoid(s)
                        Check Combi Valve(s)

                        Special Notes

                        On vehicles with rivets holding the plastic body halves of the Secondary Air Pump together check to see if the rivets are falling out. If they have fallen out or are loose you may be able to bolt the pump back together if the motor has not failed.

                          16891/P0507/001287 - Idle Control System RPM: Higher than Expected.
                          Possible Symptoms

                          Malfunction Indicator Lamp (MIL) active

                          Possible Causes

                          Throttle Valve Control Module (J338) dirty/faulty
                          Wiring/Connector(s) from/to Throttle Valve Control Module (J338)
                          Vacuum Leak

                          Possible Solutions

                          Check Throttle Valve Control Module (J338)
                          Check Wiring/Connector(s) from/to Throttle Valve Control Module (J338)
                          Check Intake System for Leaks

                          Special Notes

                          When found in the NAR 2.0T (BPY) check RVUTB: 01-09-03 or 2018919 for updated Crankcase Breather Valve
                          If the breather valve is faulty, full engine vacuum is typically found when removing the oil cap at idle.
                          When found in NAR (North American Region) 2011-2013 Jetta, Golf, Passat and New Beetle vehicles with 2.5L engine codes CBTA and CBUA see TSB 01-14-23 -or- TPI 2034012. When applicable, DTCs P050A, P0507 and P0106 are resolved after flash updating the Engine controller.

                              Thanks Rob, I’ll have a sit down and read through it all in bit, I know the secondary air pump works, I tested that through the code reader. I found one of the pipes hanging off of it and thought bingo but it’s still the same. Really useful info though mate, thanks.
