In work today is a VW Touareg with a 4.2 litre V8 twin turbo diesel , has almost 260,000km and has been having DPF , Diesel particulate Filter and EGR , exhaust gas Recirculation issues.
DPF have been removed from exhaust , and we have removed the 2 x engine ECU's , carried out a bench mode remap , to add more power and torque while coding out a few faults , turning off EGR & DPF Functions , going alot better , way more torque , no check engine lamp on dash.
Next thing is to look at the injectors as they are out of spec , which most likely is the cause of the other issues.

So if needing and faults repairing , getting that annoying check engine lamp off the dash , more power , torque - come on down and see us at

We have this 2008 mazda bt50 / ford ranger 3.0 4 cylinder diesel turbo in work.
Engine rebuild due to overheated engine , cracked cylinder wall letting water in and compression into cooling system, we have done a few of these now , getting older , still go great.
And with overheating issues we do a couple of other things with repair , like removing the Cat converter from exhaust as when they get too old or not burning off excessive heat is trapped and restricting engine causing more heat , EGR cooler leaks , putting exhaust gas into cooling system , so we have removed all , carried out a ECU remap to delete EGR system and not bring up any fault codes on dash. Make a more responsive engine and more reliable , ECU Remap helped with Rapid Performance

You don't see many of these around

1987 Ferrari 328 GTS , a 3.2 litre V8 manual kept in tidy condition , amazing what cars are hidden away.

Lucky the targa top was removed as my head was above the roof line 😄
