Seat leon cuna engined DTUK box doesnt fit my mk 3 octy VRS? why?

Featured Replies

As title basically, as far as i was aware its from a dsg leon of about same age according to the seller.

However, the loom the the fuel rail only has 2 pins, where as if you try to fit to mine the plugs on the rail have 3 pins?🤔

 

What gives?

Also just out of intrest and to confuse matters further, i also have in the garage a Blue spark tuning box from when i had a company car, it was a mk 3 octy 1.6 dsg, and again when i dug this out, it only has 2 pins.?

 

Anyone else got the DTUK tuning box and can confirm loom has 3 pins?

 

p.s.

Wondering if one of these 3 pins is just a ground or doesnt do anything, but think thats unlikely

I think i might hold off from doing that, after recent experience with this box.

I dont know if anyone else on here who owns a DTUK tuning box (the trevor one)  or used to.

But with it on my VRS it ends up throwing the coil light on and when I check the car with my scanner it comes up with a low presure fault on the fuel rail???

Which i thought was a bit confusing, as I thought the box is suppose to add more fuel and boost hence more power.

 

Instead I get the coil symbol and limp mode.

Took it off for now, as seems to be .........
