VW Audi TFSI TSI Walnut Blast Cleaning

I restore lost performance of your VW Audi TFSI or TSI engine while you wait or work from home.

If you're here it's probably time to treat your engine to a walnut blast and let it breath in more air!

 

The VW, Audi, Skoda, Seat TFSI and TSI engines are direct injection GDI engines and so suffer badly from intake carbon buildup. That's why the manufacturers recommend walnut blasting the intake area every 40k miles to maintain performance and driveability of their vehicles. 

​

Of course it's often much later than 40k miles when I get the call but generally carbon related symptoms will start to show before around 60k miles.

​

Symptoms to expect are classic intake restriction ones including:

​

- Misfire and rough idle (particularly when cold)

- Performance issues such as jerkiness and hesitance when accelerating

- Poor fuel economy

- Check Engine Light (MIL) on

​

The below before & after walnut blasting images are from a 2011 2.0 TFSI with only 60k original miles.

VW Audi TFSI TSI inlet valves before After Walnut Blast Cleaning

The carbon cleaning service I offer for the TFSI and TSI engines involves removal of the intake manifold and throttle body, walnut blast cleaning of the intake ports and valves, cleaning of any removed components such as intake manifold, throttle body, etc, and replacement of all gaskets and seals upon reassembly. Engine diagnostic checks are made before and after the service.

​

One time-consuming complication with the four cylinder engines is that the injectors normally come out when removing the intake manifold so invariably we need to remove them all and install new teflon seals, o rings, and associated clips and retainers with our special VAG seal installation tool. 

​

Pricing

​

For the four-cylinder engines this is a 6hr service at £360 for callout, labour, diagnostic checks and consumables, plus manifold and throttle body gaskets currently at £30.60, plus injector seals at £38.72 so a total of £429.32. No VAT.

 

For five, six or eight-cylinder engines please What's App or Email me with full details of your vehicle as the applications and access vary widely.

​

To perform this service I will just need an off-street location such as private driveway, and a power connection.

​

My mobile service is very popular with car enthusiasts or those that want to see exactly what’s going on with their engine at home and without the inconvenience of surrendering their vehicle to a workshop.
