For the past few weeks I have been trialling a tuning box manufactured by a German company ASA Autotechnik Saretz and I have compiled the attached report giving details of my findings. Should you want more info from me contact via a personal email and I will try to answer those questions posed.



A really special price to forum members has been negotiated with ASA Autotechnik Saretz who can offer a Tuning box, plus appropriate connecting cable complete and delivered to your door for an all-inclusive Special price of € 99 plus shipping costs of €10 to the UK. (A total of €109)

Members in other Countries should check shipping costs prior to purchasing but I have been advised that they will be as reasonable as is possible)



Please Note: -
This is a considerable saving on the regular ASA Autotechnik Saretz Internet price of €148 plus postage.



This is the best available offer on the Internet. Contact them by Email to order at

When ordering please quote reference Itza/ASA ECO CR/Special Offer


If you have another vehicle that has any other type of diesel engine, ASA Autotechnik Saretz possibly manufacture a tuning device for that as well so contact them to see what they can offer you.

Good concise report Itza.

Better than some you get from so called experts.

At present I'll leave it but may consider once warranty expires.

It doesn't affect the warranty eye30 but it is suggested that for the few minites it takes to remove/replace that you take it off before the service or trip to the shop just in case they want to be pedantic.(hope thats the right word)

The tuning box enhances your diesel experience and some think it outperforms a petrol car but my diesel does that regularly at lights without trying (oops I have a box fitted) :)

Good idea to pin this topic - can't wait til I get my tuningbox next week :)
