For reasons I won't go into, I'm finally going to install an LDA. To do this, I will follow the procedure outlined in the technical article and "tap into" the exhaust pipe at the AGR valve (2.0 TDI BKD).
Okay, so the question is, does anyone have a recommendation for a high-quality instrument?
I would like one with uniform lighting in white or blue; the color of the pointers is not important to me at the moment. VDO products are known for their good quality, but I remember that the lighting looked like the speedometer in a Wartburg.
I think we can forget about that "fluff" from FK and Co. KG; China is out of the question. I don't want a cheap trinket, but a proper instrument.
Please post recommendations for good products in the price range of up to approximately 50€ (plus or minus, of course

). It would also be great if someone could share a picture of their instrument with the lighting turned on in the dark.
You're welcome!
