I am just getting ready for the year ahead and went for the dreaded MOT all went well, needs new pads on the back and a front bearing tightenig up a tad and a head ligh adjust but the deal breaker was the emmision fail
Its a Defender 90 about 1999 on a Q pate, 300Tdi no electronics.
Got a 3.78 need 3.00 I have put injecter cleaner in the fuel an run it for a cuple of hours, done an engine oil flush with a cleaner then changed the oil change + all filters.
Is there anything I have missed that may be causing the issue and I can sort before putting it in for the re-test, all help appreciated.
