from 25 reviewsGreat selection of parts. Reasonable pricing. Fast delivery and super service/support. My new Haldex ECU worked like a charm, once the car had recognised it (took a couple of restarts of the car and fault code clearing with OBDeleven). Highly recommend!
Fantastic company, Jakub who is very helpfull and swift to reply. Helped me fix my haldex gen 5 myself, would really recommend anyone to work with or buy from this great company! Thanks again for your help Jakub
Die Lieferung kam sehr schnell an und alles war sehr professionell verpackt. Vielen Dank, ich bin sehr zufrieden!
Super komunikace, rychlé doručení - zásilka dorazila za 4 dny, po instalaci nové ŘJ mi pan pomohl nakódovat a zprovoznit. Díly pro haldex už jedině zde.
Esperienza positiva. molto professionali e disponibili. Grazie ancora. Alla prossima.
Habe einen älteren Volvo XC90, bei dem das Steuergerät für die Haldex Kupplung defekt war. Hier fand ich ein (geprüftes) gebrauchtes Gerät zu einem fairen Preis. Der Versand brauchte etwas über eine Woche, aber das war für mich ok. Allzeit netter Kontakt und schnelle Rückmeldung.
Sehr schneller Versand.
Das überholte Steuergerät funktioniert super.
Freundlicher Händler.
